0:00
then I'm here however is to predict the
0:02
future and that is very likely that
0:06
you'll want to know what gives me the
0:10
right to predict the future right I mean
0:13
what are my qualifications so I'll tell
0:16
you what my qualifications to predict
0:18
the future are my chief qualification
0:23
took place in 1952 when I found myself
0:26
in Chicago I found myself in Chicago
0:30
because I had to address the American
0:31
Chemical Society which was a thankless
0:34
task I discussed a some experiments of
0:38
mine and got very few laughs so so I
0:42
decided to visit the offices of a small
0:47
science fiction magazine called universe
0:49
science fiction at any rate I had to
0:52
think of something fast because I was
0:54
ashamed to say that I didn't have the
0:56
slightest idea of what to write and
0:58
thinking quickly I wrote a story called
1:00
Everest because though Everest was much
1:04
in the news then and I thought that
1:07
since seven expeditions had failed that
1:10
I might as well write a little story
1:11
about why expeditions failed and I
1:14
explained it by saying that the
1:15
abominable snowmen were Martians and
1:18
they kept America kept human travelers
1:22
off the top she read the story bought it
1:26
on the spot for $30 I spent half of it
1:29
in a dinner for her and me and those
1:30
days you could buy very good dinner for
1:32
two for $15 and got nowhere
1:36
went home a sadder and wiser man and
1:41
forgot about it until the next May 30th
1:44
1953 when somebody to whom I haven't
1:47
done a darn thing named Edmund Hillary
1:49
and his Sherpa sidekick tensing Norgay
1:52
climbed Mount Everest and at 11:30 a.m.
1:56
stood at the very tippy tip top they
2:05
well who was there to check up you know
2:09
and that instantly placed universe
2:12
science fiction in a very very strange
2:15
ethical dilemma if they published the
2:18
story they would make me look like a
2:19
fool and if they didn't publish story
2:22
the story they would lose $30 and it
2:25
took them a second and a quarter to
2:27
decide to publish and they did they
2:30
published in the December 1953 issue so
2:34
that there was my record as a predictor
2:37
of the future I am the only man living
2:40
who ever predicted that Mount Everest
2:41
would never be climbed five months after
2:48
I will now talk about the future and the
2:56
first thing we have to remember that
2:57
you're only safe if you predict the
3:01
obvious the fact that the abominable
3:04
snowmen were Martians we're nada was not
3:06
obvious probable perhaps but not obvious
3:11
so to predict something that's obvious
3:14
let's predict that the population of the
3:17
earth will go up after all it's been
3:20
going up ever since the beginning of
3:24
human history as far as we know in fact
3:26
the only century that we know of in
3:28
which the human population dropped all
3:30
over the world was in the 14th century
3:32
as a result of the depredations of the
3:36
Black Death during which one-third of
3:38
the entire human race was killed off in
3:40
the space of maybe 25 years and it took
3:43
the human species a full century to make
3:47
up that loss and you might wonder
3:50
because these days we could do that and
3:52
maybe 20 years and see why are you see
4:02
and you may wonder why it took them that
4:05
long in the old days and think that
4:08
perhaps they didn't know the secret well
4:10
I have every reason to believe they knew
4:14
the secret and worked away at it as
4:16
assiduously as honest people do today
4:20
what happened was that although many
4:22
children were born many children died
4:25
the death rate was high in those days
4:27
and the rate of increase was low since
4:31
then we have managed to improve matters
4:35
and that reminds me of how difficult it
4:38
is to know a dangerous scientific
4:41
discovery when you hear one I mean
4:44
everybody is against all kinds of
4:48
technological advances that seem
4:50
dangerous large automobiles gas guzzling
4:54
monsters nuclear fission plants these
4:59
aluminium beer cans all sorts of things
5:02
people scorn scorn is there anything
5:05
they like yes cancer research they like
5:08
research into all kinds of diseases
5:11
that's good they say why are we busy
5:14
going off into space why don't we spend
5:17
our time trying to cure cancer that's
5:20
because most people don't expect to go
5:22
into space but most people expect to run
5:24
the risk of cancer but if you stop and
5:28
ask yourself what is the most dangerous
5:30
discovery that was ever made the answer
5:33
was the germ theory of disease which
5:35
came out in the 1860s because as the
5:38
result of actually learning what caused
5:40
infectious disease we gradually learned
5:43
how to take measures that minimised
5:45
infectious disease helped cure it if it
5:49
was caught and eventually through the
5:52
conquest of infectious disease we
5:54
doubled the lifespan of the human being
5:57
from an average of perhaps 35 to an
5:59
average and the more quote advanced
6:02
unquote nations of perhaps seventy so
6:05
every one of us lives twice as long as
6:07
he would have lived if he had lived say
6:09
120 years ago which is nice
6:12
most people don't object to that but it
6:17
does leave us with a population
6:18
explosion because as a matter of fact
6:22
what governs the Earth's population is
6:25
the birth rate and the death rate if the
6:28
birth rate is higher than the death rate
6:30
the population goes up or if you want to
6:33
look at it another way if the death rate
6:35
is lower than the birth rate the
6:36
population goes up and vice versa if the
6:39
birth rate is lower than the death rate
6:42
or the death rate is higher than the
6:44
birth rate have I got it all straight
6:45
doesn't matter so college audience I say
6:48
I say what I please and you sort it out
6:51
because you know what I mean now right
6:57
now the birth rate is going the right
6:59
now the population is going up fast not
7:02
faster and faster and ER at the present
7:04
moment I think it stands at something
7:07
like one point six percent per year
7:10
about five years ago it was almost 2
7:13
percent per year it's been going down
7:15
slightly because they say the birth rate
7:17
in china has fallen we have the chinese
7:20
word for that i don't know how they've
7:24
managed it I think by moral suasion they
7:28
sent around the CAD Rees from house to
7:30
house and they spend time talking to the
7:32
young wives and they spent so much time
7:34
talking she doesn't have time to raise
7:36
the birthrate but even so at one point
7:40
six percent that's 72 million people
7:44
each year additional and 72 million is
7:49
about the population of Bangladesh
7:51
almost so that it's as though we've got
7:53
a new Bangladesh on earth every year and
7:57
we haven't yet arranged to take care of
7:59
the original Bangladesh question is what
8:02
are we going to do about it and we've
8:06
got to go back to that birth rate death
8:07
rate business there are only two ways of
8:10
handling and expanding population if you
8:12
think that it's dangerous and if you
8:15
want to establish population of
8:17
stability or even reduce the population
8:19
to a reasonable level only two ways to
8:22
you can either raise the death rate
8:25
until it's higher than the birth rate
8:26
or you can lower the birth rate until
8:28
it's lower than the death rate
8:30
fortunately those are the only two ways
8:32
if there were 50 ways every way would
8:35
have its adherents and be a very big
8:37
mess as it is we just count how many
8:41
people favor raising the death rate how
8:44
many people favor lowering the birth
8:45
rate of course there might be some
8:48
people who say I don't want to do
8:50
anything just let things go and the
8:54
beauty of it is that that will raise the
8:57
death rate which is the advantage of
8:59
raising the death rate you don't have to
9:01
do anything no hard decisions no
9:05
political difficulties no sacrifices
9:08
just go on do exactly what you've been
9:10
doing population will go up the death
9:13
rate will also go up eventually and
9:15
bring the population down only trouble
9:19
is that's what we call catastrophe
9:21
because the methods for raising the
9:23
death rate are also limited you can do
9:26
it by violence such as war or terrorism
9:29
or civil strife doesn't matter kill off
9:32
people in anger or by disease or by
9:39
there's your choice all through history
9:42
all through the history of life whenever
9:46
a species has increased its numbers to
9:49
the point where it outstripped its food
9:51
supply that has always redressed its
9:56
numbers by an increase in death rate
10:00
it's Nature's Way if you like things
10:04
that are natural you'll be crazy about
10:12
however human beings are the only
10:14
species that ever existed on earth who
10:18
are capable of foreseeing the future if
10:21
perhaps not in detail then in broad
10:24
brushstrokes show a human being a
10:27
situation in which the population is
10:29
going up and the food supply is going
10:32
down and by dint of considerable hard
10:35
thought that will eventually occur to
10:38
him that this will end in famine and it
10:42
may be that he doesn't like famine
10:45
because he suspects that it may not
10:48
strike other people only in which case
10:52
he may decide to do something about it
10:55
which is to increase the food supply or
10:58
decrease the population now of course
11:01
everyone says right away well let's
11:03
increase the food supply for goodness
11:05
sakes it can be done we can support 4
11:08
billion people what's needed is not more
11:11
food we have plenty of food just
11:13
distributed more decently fix it so that
11:17
everyone gets his fair share fix it so
11:20
that governments are sane and don't do
11:24
things that are stupid fix it that
11:26
people are honest and unselfish and
11:28
share with each other
11:29
fix it that the economic system is
11:33
honest and trade is efficient and
11:35
everybody works decently and if pigs had
11:39
wings they would fly but even if that
11:44
happened in about 40 years there'll be 8
11:47
billion people on earth and if you've
11:49
managed to keep up with that and 40
11:52
years more there'll be 16 billion people
11:54
on earth and in a little while 250 years
11:58
to be exact the total number of
12:00
population on earth will be such that
12:03
the average density will be 100,000 per
12:07
square mile now 100,000 per square mile
12:10
is something that's easily described for
12:12
those of you who have ever been in
12:14
Manhattan at lunch hour
12:17
that's it I'm there every lunch hour I
12:21
know exactly what it looks like people
12:24
all over the streets wall-to-wall with
12:27
lots more hidden in the skyscrapers and
12:29
in 250 beg you partners at 250 years
12:33
though it's 450 I wouldn't lie to you
12:36
and 450 years of the present rate the
12:39
population doesn't see the world over
12:41
will be a hundred thousand per square
12:43
inch not only a nice places like the
12:45
Berkshires but in Greenland Antarctica
12:51
the Himalayan mountains the Sahara
12:53
Desert and if you'll throw planks across
12:56
the Pacific and Atlantic Ocean on them
12:58
too and you have the feeling that you're
13:01
going to have one world girdling
13:04
skyscraper parsha partially apartment
13:07
houses partially factories partially
13:09
partially all kinds of things schools
13:11
colleges and the entire ocean taken out
13:15
of its bed and placed on the roof of the
13:19
globe-girdling and growing and growing
13:22
algae or something like that
13:25
because all those people will have to be
13:29
fed and the only way they can be fed is
13:31
to allow no waste whatever item1 no
13:34
competition so as you can't feed other
13:37
creatures - as well as human beings that
13:40
means not only no more semadar and
13:44
Burmese - ERISA's no more California
13:49
condor it means no more Pussycats no
13:52
more puppy dogs no more gold fishes no
13:56
more caterpillars no more nothing except
13:58
human beings and of course they can't
14:01
live on something which has waste can't
14:03
waste the thing we've got to grow
14:04
something which is 100% edible like one
14:07
celled creatures and for goodness sakes
14:10
you have this ocean on the apartment
14:13
house roof boiling away in the Sun just
14:17
frothing over with algae and everyone
14:19
Somalia have thick conduits leading down
14:22
the ocean water from which you take out
14:23
the algae and all the other plankton or
14:27
whatever the heck it is and you pound it
14:29
and you separate it and you Flay
14:31
you cook it finally you have your pseudo
14:34
steak and your mock veal and your
14:37
healthful sub vegetables and so on and
14:41
then you send the water it's left over
14:44
up there but you have to grow some more
14:45
algae in addition to the algae unit
14:48
exists you're going to have to fertilize
14:49
them give them nutrients where can you
14:52
get your nutrients from fruits god sakes
14:54
only from chopped up corpses and human
14:57
wastes so you've got other conduits
15:00
leading upward this is not exactly such
15:04
a good world but maybe if we manage to
15:06
make it will be used to it and we'll say
15:11
except that in 40 years more the
15:13
population density of the earth will be
15:15
200,000 per square mile obviously in a
15:19
relatively short time like for instance
15:22
3,000 years the total weight of flesh
15:24
and blood will be equal to the total
15:26
weight of the earth and the 9,000 years
15:29
it'll be equal and total weight of the
15:31
known universe so let's face it sooner
15:37
or later we'll have to stop we can't not
15:39
do anything either to populate either
15:42
the death rate will go up or the birth
15:44
rate will go down and I personally
15:46
prefer that the birth rate go down
15:48
question is house is going to happen
15:50
because the disadvantage of using the
15:53
birth rate going down as a method of
15:55
controlling population is that it's
15:57
never been tried really and we don't
15:59
know if it'll work so certainly we're
16:02
going to have to use some method that's
16:03
never been used and I've got a method
16:06
believe it or not I have noticed that
16:09
throughout history whenever the
16:10
birthrate has been high the social
16:12
status of women has been low and this
16:16
makes sense this is not a pure
16:18
coincidence this is reasonable because
16:21
if a woman has a lot of babies and if
16:24
each one takes nine months and so far
16:27
this is one thing the Industrial
16:32
not been able to change nor does it help
16:35
to get more men on the job and besides I
16:42
don't know if any of you people have
16:43
noticed it but after the baby is born
16:45
and hangs around the mother an awful lot
16:48
for a while and before the baby stops
16:52
hanging around the mother there's
16:53
another one on the way and then another
16:55
one than another one and the woman has
16:58
all she can do to bear the babies and
17:00
suckle a babies and take care of the
17:02
babies and clean the house and cook and
17:04
pull the plow and the horses and feeling
17:06
good and things like that and under
17:10
circumstances like that you're going to
17:12
waste time educating a woman for what
17:15
you're gonna waste time expecting her to
17:17
do things that are human like helping to
17:21
run the world of course not poor thing
17:23
is enough work to do so she just stays
17:27
there ignorant and without shoes and
17:29
working away until she dies but then
17:32
she's easy to replace on the other hand
17:36
and those periods in world history not
17:40
too long and those areas not too
17:43
extended in which women have had
17:45
reasonable treatment treated as kind of
17:53
the birth rate has dropped automatically
17:56
in fact people right away start worrying
17:59
about race suicide as soon as the birth
18:01
rate drops never worry about race
18:03
suicide as the population goes up this
18:06
is a peculiarity of the human species
18:08
and you say why on earth should the
18:13
birth rate drop since the highest since
18:16
absolutely the highest calling any woman
18:18
can possibly aspire to is that of being
18:21
a wife and mother what else can she
18:24
possibly want to do you hear all over
18:27
the place about how great it is
18:28
motherhood you know and I was mistrust
18:31
that because I always figure that
18:34
anything that has to be pushed that hard
18:36
can't be that good I figure nobody goes
18:51
you know it'll keep your strength up
18:55
nobody goes around with billboards
18:58
saying don't be a fool breathe so that
19:05
when you're forever being told how great
19:07
it is to have lots of children I figure
19:10
someone's getting something out of it
19:12
besides I figured were having children
19:14
of that great men have figured out a way
19:18
mind you I'm not against children I have
19:21
two of my own of course when I said to
19:24
my own they didn't do much no no man
19:27
ever does but still I wouldn't want
19:32
people not to have any children because
19:34
if children stop altogether then the
19:36
human race comes to an end in less than
19:38
a century no matter how many of us there
19:40
are but to say you don't want no
19:43
children doesn't mean you want all women
19:46
to be baby machines there's such a thing
19:48
as moderation one or two children is
19:50
plenty can a woman be satisfied with one
19:55
sure she can why not it isn't so great
19:59
having a lot of children if you have
20:01
nothing else to do certainly and the
20:03
population will automatically drop and
20:06
in addition the brainpower of the human
20:09
species will automatically be doubled as
20:12
far as honest use of it was concerned
20:14
without adding a single person to the
20:16
actual population might be more than
20:19
doubled we've never given women a chance
20:21
they may be smarter than us
20:26
of course some men are afraid of this
20:29
they feel that they'll be sharing some
20:31
of their precious privileges don't look
20:35
at it that way you're sharing some of
20:37
your responsibilities my own feeling is
20:40
it's about time that women did half the
20:43
work in the world and and took half the
20:51
risks and half the blame and all the
20:52
rest of it thank who knows the last act
20:57
of male chauvinism on earth may be that
21:00
of forcing women to take their share
21:02
much against their will too darn many
21:05
women are so happy at having hats taken
21:08
off in their presence and being helped
21:10
across the street that they don't mind
21:13
being slaves in exchange and I say we
21:15
don't need this kind of women so there's
21:20
my solution you'll give women equal
21:22
rights and every possible respect part
21:25
of the birth rate will go down the
21:27
population will be stabilized
21:29
Matthieu humanity will survive so that
21:33
women's lib is vital not only for women
21:36
but for men too of course people people
21:42
say to me how are you going to persuade
21:44
all the different places on the earth to
21:47
grant equal rights to women even macho
21:49
communities like south of the border and
21:52
old and old traditional places where
21:57
women have for thousands of years been
22:00
considered a domestic animal somewhat
22:03
higher than the ox perhaps but
22:06
definitely lower than the horse and I
22:11
I feel that what's going to happen is as
22:15
population goes up is going to be clear
22:19
to governments all over the world that
22:21
things are just going very bad and I'll
22:26
have to do something and I'm convinced
22:28
that there'll be no way of handling the
22:31
problem humanely except by giving women
22:35
equality forcing women to accept really
22:37
quality of course you know what human
22:41
beings are like they may prefer inhumane
22:43
methods like forcible sterilization like
22:47
massacres like all sorts of fun things
22:50
like that there and to people who are
22:53
against birth control I suppose this is
22:56
preferable at least I can't imagine why
22:59
else they should be opposed to birth
23:00
control well then if we manage to
23:05
control the population what next the
23:10
difficulty is of course that there is
23:14
60 billion barrels of oil and the 600
23:18
billion barrels of oil on the ground and
23:20
we're consuming 30 billion barrels a
23:23
year 20 billion barrels a year if you
23:25
divide 600 billion by 20 billion and you
23:28
keep the zero straight the answer is 30
23:30
which means that the present rate of use
23:34
we've got enough oil to last us 30 years
23:37
and after that were in trouble is plenty
23:39
more energy but we're geared the earth
23:42
is geared to the use of oil which is by
23:44
all odds the cheapest the most
23:46
convenient energy source we've ever had
23:48
to develop other energy sources is going
23:51
to mean a capital investment and it's
23:54
going to mean a lot of maintenance and a
23:57
lot of research and a lot of trouble so
24:01
what we ought to do is start going
24:04
through all this trouble and all this
24:06
expense and all this effort and all this
24:08
emotional turmoil right now and conserve
24:12
our fossil fuels as much as we can so as
24:15
to give us as much lead time as possible
24:17
and this is going to be difficult and
24:22
the only thing in its in its favor is
24:25
may save civilization for those of you
24:27
who think it's worth saving for those of
24:31
you who don't you might recall that if
24:34
you don't save it we lose several
24:36
billion lives the world over of which
24:39
your own may be won and if you still
24:43
don't think that's important
24:45
then you're fortunate nothing can happen
24:47
to you that's important now where are we
24:52
going to get energy from this plenty of
24:54
energy in the universe this plenty of
24:57
available energy in the universe
24:59
it just means learning how to use it and
25:01
what we want there are all kinds of
25:04
energy I won't bother listing them all
25:06
because this is you can't pick up a
25:07
newspaper or a magazine without there
25:10
discussing different energy sources
25:11
we'll take it as read there are all
25:13
kinds of energy sources and we can use
25:15
them all because in some places on earth
25:18
and it's sometimes and for some purposes
25:20
one particular energy source may be
25:22
particularly convenient heck there many
25:25
times when human muscle is the most
25:28
convenient energy source although this
25:30
gets hard to believe but try
25:34
reproduction without the use of human
25:36
muscles and you'll see what I mean it
25:38
doesn't work with windmills well what we
25:43
need though backing up all this is some
25:46
form of energy which is copious safe and
25:49
eternal by copious I mean there's enough
25:52
of the energy to supply Earth's entire
25:55
needs even if all other sources of
25:58
energy were discounted by safe obviously
26:01
I mean that there are no side effects
26:04
resulting from the use of energy which
26:06
can cause harm and eternal means well it
26:10
sounds like it means lasting forever but
26:13
supposing we limit it and say it lasts
26:15
as long as as humanity does is it all
26:19
if it runs out when we run out there's a
26:21
species okay then let's take these one
26:26
that I cut one at a time what's copious
26:30
there are only two forms of energy that
26:34
are really copious in the sense of
26:39
being copious one is nuclear fusion this
26:43
is not to be confused with nuclear
26:45
fission which we have now nuclear
26:48
fission is very useful it works we know
26:52
that keeps New England warm during the
26:54
cold winters when Ohio freezes to death
26:57
because one year it's natural gas the
27:00
next year it's coal meanwhile New
27:02
England has no problems it has nuclear
27:05
plants which produce the electricity and
27:08
it can ship electricity to other parts
27:10
of the country you don't like nuclear
27:12
plants I don't blame you but you use the
27:14
electricity it produces it's one of
27:17
those things you demonstrate against
27:18
nuclear plants but you don't turn off
27:21
the electric switches so that I
27:30
I beg leave to sniff a little hypocrisy
27:33
here but well if you prefer to sniff
27:44
nuclear fusion on the other hand has an
27:47
easier source it's heavy hydrogen not
27:50
uranium heavy hydrogen can be gotten out
27:53
of the oceans not only that it delivers
27:57
seven times as much energy weight for
27:59
weight as nuclear fission does it
28:02
doesn't form nuclear wastes it does form
28:05
trittye it does involve tritium and
28:07
neutrons which we hope will produce a
28:11
far lesser problem than the radioactive
28:14
ash that the fission plants do and it is
28:19
available everywhere
28:20
since water is practically a universal
28:23
commodity except in some deserts where
28:25
very few people live anyway there's only
28:28
one catch with nuclear fusion which by
28:30
the way will last for billions of years
28:33
there's only one catch not as we haven't
28:35
got it yet and we don't know when we'll
28:38
have it I feel we'll have it before long
28:41
but we haven't got it yet and when we do
28:44
get it it'll take perhaps 30 years
28:48
before we can build a large nuclear
28:52
fusion power plant and get all the bugs
28:54
out of it and there are some people who
28:56
suspect that the bugs will be
28:58
sufficiently complex so that we may not
29:02
be able to make use of it after all I
29:04
hope that these pessimists are
29:06
confounded but we can only wait and see
29:09
meanwhile we can't afford to attempt
29:13
nuclear fusion alone or entirely we must
29:17
go to the other source of energy which
29:20
is copious can support us all safe
29:23
produces relatively little in the way of
29:25
injurious side effects and eternal will
29:28
last as long as humanity well and that
29:30
of course is the Sun and since this is
29:35
Sunday I say to the proper reverence if
29:38
we can use Sun power I don't mean just
29:42
in low intensity situations as in
29:46
warming houses I mean by conversion into
29:49
electricity which is a high intensity
29:53
sort of thing that can be done with
29:55
prescient techniques we have
29:57
photoelectric cells we have solar
29:59
batteries we can expose wafers of
30:03
silicon to the sunlight and build up an
30:06
electro-motive force and create an
30:08
electric current we have to it's poor
30:11
low efficiency thing so far and quite
30:14
expensive so far and sunlight is very
30:17
dilute there's a lot of sunlight but
30:19
it's spread out so that we would have to
30:22
coat thousands of square miles of desert
30:25
area so to get maximum Sun and even then
30:29
it wouldn't be working twelve hours out
30:32
of every 24 and the average because you
30:34
don't pick up much in the way of
30:35
sunlight at night and there's so far no
30:40
efficient way of storing electricity so
30:43
that we can we can pick up a lot of end
30:47
electricity during the day and then use
30:49
the stored electricity at night you
30:51
would have to have stations at opposite
30:54
ends of the earth different places that
30:55
always be some in daylight and of course
31:00
also even the the air does stop and
31:04
absorb a certain amount of solar energy
31:06
no matter how clear it is at any time it
31:08
gets misty and foggy and cloudy it loses
31:12
a lot more and you can't help but think
31:14
how much more efficient it would be if
31:17
we could build the solar power
31:19
collecting stations in space put them up
31:22
over the equatorial plane at a height of
31:25
20 mm plus miles and have it revolve
31:28
around the earth in 24 hours
31:30
synchronous revolution about the earth
31:32
so that are always stay more or less
31:35
over one spot on earth it would absorb
31:38
sunlight the full range of solar energy
31:40
never in any way stopped depleted
31:43
absorbed by anything at all hardly ever
31:47
be in the Earth's night shadow under
31:50
ordinary conditions would mist they
31:51
thinned the shadow the tapering schnike
31:54
beam at a height of 20 mm plus miles and
31:59
would only pass through at a certain
32:01
period of time before and after the
32:05
and over the space of a year it would
32:07
spend only 2% of its time in the shadow
32:09
and of course you would have a number of
32:11
them all around the earth and they could
32:13
supply the whole earth with energy
32:16
beaming him down in the form of
32:18
microwaves to be absorbed on earth with
32:22
much greater efficiency than undiluted
32:24
sunlight is of course we know that
32:28
microwaves can be dangerous we're not
32:32
going to beam them down in the middle of
32:34
Amherst even though some of you may
32:38
think it's a good idea and there is
32:43
every reason to think that we can't
32:45
arrange it so if anything goes wrong the
32:48
beam is instantly dispersed becomes only
32:51
minimally dangerous and is stopped
32:53
naturally you wouldn't want to move
32:56
through the beam but presumably
32:59
airplanes will know how to avoid it and
33:01
even if they do go through it they will
33:03
remain through it so small or so so
33:06
short a time that the danger is minimal
33:09
birds flying through it if they decide
33:11
to pause on the wing while in it and fly
33:14
round and round and round may eventually
33:17
come out broiled but I have every reason
33:22
to think that birds won't do it even if
33:25
you beg them to it may work there's the
33:30
danger of thermal pollution that is that
33:33
is heat is added to the earth which it
33:36
wouldn't otherwise get so that the
33:38
average temperature of the earth would
33:39
go up and you would that would limit the
33:43
amount of energy you could receive from
33:45
such solar stations because if you raise
33:48
the temperature of the earth
33:49
sufficiently while you'll melt the ice
33:51
caps and raise the water level of the
33:55
oceans 200 feet and drown all the
33:57
coastal plains of the world which are
34:01
precisely the most populated regions
34:04
well if we wouldn't with this would this
34:09
doesn't mean we can't use any amount of
34:12
heat just not too much it still leaves
34:15
us a liberal supply until such time
34:19
as we learn how to help the earth
34:20
radiates the excess heat
34:23
well now what else is good about this
34:26
thing which is generally considered a
34:28
kind of feat of fantasy hard-headed
34:32
people are against such solar power
34:34
stations for a variety of reasons they
34:38
say you realize how expensive it is sure
34:42
sure I realize how expensive it is it's
34:45
likely to take a hundred billion dollars
34:46
a year say over a space of 20 I'm sorry
34:50
100 billion dollars over the space of 20
34:52
20 years we should say 5 billion dollars
34:54
a year who's going to spend 5 billion
34:57
dollars a year it's a lot of money it's
35:00
more than tuition right now
35:10
but the people who are worried about
35:12
five billion a year don't realize that
35:14
we spend a lot more than that on booze
35:16
and a lot more than that on smokes and
35:21
no one has ever said that the space
35:23
program does any more harm than waste
35:25
money there are rumors the tobacco and
35:28
alcohol do actual harm beyond the waste
35:32
actual physical harm of course they also
35:37
bring pleasure and people say this is
35:39
cheap of you Asimov since you don't
35:41
smoke and don't drink to cast aspersions
35:44
upon other people's pleasures and imply
35:47
that they should easily sacrifice them
35:50
for something you were interested in and
35:52
I recognize the Justice of this and I
35:56
sniff a certain amount of hypocrisy and
35:59
myself when I talk this way but then
36:04
supposing we consider war and
36:07
preparations for war now who it gets
36:10
personal pleasure out of war who really
36:15
considers it a fun activity these days
36:19
nobody is going to admit in public he
36:22
wants war he enjoys it because the
36:24
excitement makes his blood race through
36:27
his veins and just gives them that good
36:30
old tingly feeling everyone gets up and
36:34
says I hate war but we have to be
36:36
prepared as a deterrent right so that
36:39
the world now spends four hundred
36:43
billion dollars every year to support
36:45
its various war machines its various
36:48
competing war machines four hundred
36:51
billion every year I used to say three
36:53
hundred billion now it's kind of four
36:54
hundred billion by the year 2000 the
36:56
present rate of increase it'll be one
36:57
trillion a year if we get there which I
37:00
doubt well for goodness sakes what is
37:03
the four hundred billion dollars a year
37:04
buying us what good are no war machines
37:07
we can't use them we can't have a
37:10
thermonuclear war at all because it's
37:13
universal destruction as a matter of
37:16
fact it doesn't supply a thermonuclear
37:18
war doesn't supply us
37:20
with the minimum virtue of a war which
37:25
is one of the reasons I don't think
37:26
it'll be fought you see the thing with a
37:28
thermonuclear war is we have every
37:30
reason to think it'll s maybe a day and
37:32
a half and then a day and a half there's
37:34
no time for promotions to come through
37:46
it's worse than that you can't even have
37:50
regular Wars you can't even have the
37:53
kind of wars we once had in the good old
37:55
days the fun Wars like World War two I
38:00
mean you can imagine the Soviet Union
38:02
the United States getting together in
38:04
deciding the generals are rusty and they
38:06
need a war but c'mon fellas on a bright
38:08
we won't use nuclear weapons we won't
38:10
use jet planes we're going to build us a
38:12
lot of World War 2 artillery and planes
38:14
and tanks and we'll fight it like
38:16
gentlemen so so they'll draw along down
38:20
the middle of a neutral nation and
38:21
they'll line up you guys are so naive
38:28
that's what neutral nations are for for
38:30
the decision and you'll line up and
38:37
either side and for four or five years
38:39
maybe six if it's too exciting to stop
38:42
you have frontal penetrations and flank
38:45
attacks and artillery bombardments and
38:47
bombing attacks and then maybe if you
38:49
want some sort of old-fashioned
38:51
excitement poison gas things like that
38:54
at the end of the time at the end of the
38:56
time you should you see who's where who
39:00
has accomplished what how many people
39:01
have been killed and you assign
39:02
indemnities and orange exchanges of
39:05
territory and all that losing side
39:08
shoots as generals now that's that's the
39:11
great problem I've always maintained
39:12
that if the losing side in any war
39:14
automatically shot his generals and if
39:16
the generals were told this in advance
39:17
there never be any Wars because the
39:19
generals will always say they weren't
39:21
ready but you don't do it that's
39:24
considered not sporting but why can't we
39:28
fight a war like that easy we don't have
39:30
the gasoline for it anymore
39:31
you know how much gasoline it takes to
39:33
run even a world war two war nowadays
39:35
more than we can afford to spend
39:37
considering we've only got a thirty year
39:39
supply left and don't tell me we're
39:42
going to find more gasoline supply
39:45
petroleum supplies no matter how much we
39:47
find it may extended another ten years
39:50
no more heck you can't even fight little
39:54
Wars anymore I mean supposing you have a
39:57
war between two small
39:58
nations that don't have nuclear weapons
40:02
they're forced to fight it with
40:04
non-nuclear weapons naturally neither
40:07
one is going to fight it unless they can
40:11
get the weapons from one of the great
40:13
powers so that they can have really
40:15
sophisticated non-nuclear weapons
40:17
otherwise there's no fun in fighting the
40:19
well that means one side calls in the
40:22
Soviet Union the other side calls the
40:24
United States now they fight the war can
40:31
after six days one side may be winning
40:34
whereupon the other side has to be
40:36
helped by its nation even more because
40:38
they don't want to lose face which means
40:40
the other nation has to help its side
40:42
before you know it you've got a
40:43
thermonuclear war so if there's any
40:45
danger of one side winning and usually
40:47
that's that's pretty determinable after
40:50
six days is anything that they they stop
40:52
it happens all the time the other kind
40:56
of a war is when you have a small war
40:58
where the great powers aren't interested
41:00
this hardly happens anymore in which
41:03
case they fight with slings and arrows
41:04
of outrageous fortune and it takes them
41:08
17 years to kill a hundred people and
41:11
nobody cares or you can have terrorism
41:15
you can always have terrorism because
41:17
all it takes is five men or women you
41:19
call yourself the cosmic international
41:21
army of human righteousness and when no
41:31
one is looking you shoot people in the
41:32
back and you proudly proclaim it in
41:37
secret messages where no one is looking
41:39
and say how brave you are
41:43
well you get the headlines you get
41:46
pictures in the paper if you happen to
41:49
be caught and imprisoned your comrades
41:51
kill somebody else to get them to
41:53
release you and it's more fun than you
41:55
can shake a barrel of a barrel of
41:57
monkeys that the only thing is it never
42:00
accomplishes anything it just never does
42:02
in the whole history of mankind
42:04
terrorism has never accomplished
42:06
anything except when it's backed by an
42:08
official army and these days we can't
42:11
have an official army backing it because
42:13
the whole thing is we can't fight a war
42:14
so it's just terrorism all by itself you
42:17
get nothing out of it except newspaper
42:19
headlines television coverage a little
42:23
pain and discomfort to individual people
42:25
and if you're not directly involved you
42:28
can endure it philosophically and
42:31
therefore what the heck is the whole use
42:34
of this entire military machine you say
42:38
is it deterrent just to make sure
42:43
except that just keeping a military
42:45
machine in being is extremely expensive
42:48
and and wastes a huge amount of energy
42:51
and accomplishes nothing but destruction
42:55
we're going to be destroyed by military
42:58
machines even if we don't use them and
43:01
yet we spend 400 billion dollars a year
43:04
as a quick road to suicide and we don't
43:09
feel we're wasting the money for one
43:11
thing we're going to get our money's
43:12
worth we want suicide we'll get suicide
43:14
no question of being cheated but if
43:17
someone were to suggest spend five
43:18
billion dollars a year for a sure source
43:21
of energy which will be serviceable for
43:24
the entire world you holler expense
43:27
expense it's four hundred million
43:30
dollars a year for destruction not one
43:33
penny for salvation this is the new cry
43:36
of all the hard-headed critics and the
43:39
only reason they're hard-headed is cause
43:41
solid bone from ear to ear
43:51
now let's suppose we have these solar
43:54
power stations we're building them we
43:55
found the money well heck we were going
43:58
to get the material from you know earth
44:00
is running low on all sorts of resources
44:03
how are we going to build a hundred
44:04
power stations up there along with all
44:07
the spaceships it takes and all the fuel
44:08
it takes and so on well for one thing as
44:11
far as material is concerned we've got a
44:13
beautiful piece of real estate up there
44:16
in the moon the moon is 181st the mass
44:21
of the entire Earth and it's only there
44:23
two hundred and thirty seven thousand
44:25
miles away you say listen that's a long
44:27
distance no it isn't it's three days
44:29
away it's three days away we have sent
44:34
let's see now 15 people to the moon
44:36
twelve mate at three didn't but every
44:38
single one of them got back you can't
44:40
get safety records like that almost
44:41
anywhere and that even though they wrote
44:45
wrote on ships which were the best you
44:47
could build with the lowest bidders and
44:52
now Columbus he did something that was
44:55
difficult I don't want to run down the
44:57
astronauts believe me you couldn't get
44:59
me on a you couldn't even get me in an
45:01
airplane but nevertheless the fact
45:04
remains if I had my choice I'd rather go
45:06
with Neil Armstrong than with
45:09
Christopher Columbus Columbus had three
45:11
ships that was salvaged that was
45:14
salvaged on the point of sinking any
45:17
what if sunken any stone in fact coming
45:20
back a stump did sink the Santa Maria
45:22
but going there he hid the only seven
45:24
week stretch in the history of the North
45:26
Atlantic without a storm what's more he
45:31
didn't know where he was going he
45:33
thought he was going to Asia he didn't
45:35
make it frankly and it's and as for the
45:38
crew they didn't know any with anything
45:40
about where they were going there was
45:41
nothing with the heck you go to the moon
45:43
you've got it easy a drive to the top of
45:45
the atmosphere look around there's the
45:51
you aim at it and furthermore if you're
45:57
going to the moon you knew for sure that
45:59
they weren't going to be hostile natives
46:01
there so on the whole going to the moon
46:05
is easy in terms of our technology today
46:09
it's much easier then Columbus is struck
46:12
to America so we go there and we set it
46:14
up as a mining station we can get
46:16
everything from the moon that we need
46:17
except carbon hydrogen and nitrogen and
46:20
that earth will supply for a while of
46:23
course lots of people are horrified they
46:25
say gee we've been we've been mucking up
46:27
the earth now we're gonna go there and
46:29
muck up the moon too and my answer is
46:32
why not the moon doesn't belong to
46:35
anybody there is no life on the moon of
46:42
any kind there aren't even any germs to
46:46
give you concern over you know bacterial
46:56
now there are two things that concern us
46:59
on earth one is that the moon looks
47:01
pretty and you don't want it sort of
47:03
them you don't want it more feet
47:08
fortunately fortunately Providence and
47:12
its infinite wisdom has decreed that the
47:15
moon presents one face only to the earth
47:18
at all times you know I have a feeling
47:21
I've been neglecting you people and this
47:28
means that we can work on the other side
47:32
where no one standing on earth will ever
47:34
see the moth-eaten as' the other fact is
47:39
that the moon thanks to its mass does
47:42
create the tides and if we reduce the
47:45
mass we reduce the tides and we might
47:48
not like this but I assure you that all
47:50
our fooling around on the surface of the
47:52
Moon and digging up or etc is going to
47:55
take thousands of years before we make
47:58
the slightest perceptible diminution of
48:01
its mass so I think we can use the moon
48:04
fine and of course it's not going to be
48:09
useful to commute to outer space and to
48:14
the moon in order to build the space
48:16
power stations very expensive to send
48:20
people up at 8 a.m. and bring them down
48:22
at 5:00 p.m. you know what you really
48:26
need a space colonist space settlements
48:29
you'll have people living in space
48:31
settlements and they'll be doing the
48:32
work course that'll be interesting that
48:36
as they do the work other space
48:40
settlements other power stations
48:43
they'll be quickly returning profits on
48:46
the initial investment not only will the
48:48
expense be far less than that which is
48:51
produced by the by the competing
48:55
military establishments but whereas the
48:57
competing military establishments never
48:59
return a profit these space activities
49:02
will in the form of energy eventually
49:04
and in the space of a few decades we'll
49:07
be getting far more back in the way of
49:09
energy than we ever spent building them
49:11
in fact we can build all kinds of things
49:14
in space one thing one advantage space
49:17
has is is lots of room there we can
49:20
transfer observatories into space we can
49:23
transfer laboratories into space we can
49:26
transfer industries into space where
49:28
they can take advantage of hard vacuum
49:31
of high and low temperatures of hard
49:33
radiation of gravity free conditions all
49:37
sorts of things will make it possible
49:38
whom possible for them to produce all
49:41
kinds of industrial cybernetic etc
49:45
etcetera acts tools devices that either
49:50
can't be performed it can't be formed on
49:52
earth at all or only with the greatest
49:54
difficulty fact space may be the Japan
49:58
of the 21st century furthermore if we
50:04
get if we get as many as much of our
50:07
industrial establishment into space as
50:09
possible why we'll get rid of the side
50:13
effects of Industry lots of people who
50:14
don't like what the Industrial
50:16
Revolution has done to man they make use
50:19
of all its advantages but they don't
50:21
like its disadvantages and they would
50:23
like to see get rid of our industrial
50:27
society provided they can think of some
50:29
way of doing it without losing their
50:31
firm grip on the advantages you know
50:34
it's these people who denounce the
50:37
automobile and strum away on their
50:40
electric guitars anti automobile songs
50:43
so I say if you get industry into space
50:48
you are in a sense getting rid of at
50:51
least some of the disadvantages of our
50:53
industrial civilization and saving its
50:57
advantages they're not far away only a
50:59
few thousand miles but all their waste
51:02
matter all their pollution all their
51:05
noise all their whatever you don't want
51:07
is up there you don't even have to send
51:09
many people up there because undoubtedly
51:11
if civilization continues they'll be
51:13
automated and computerized to a
51:15
fare-thee-well and with everything up in
51:18
space none of it actually belongs to any
51:20
particular spot on earth it would pay F
51:23
body on earth to contribute all they can
51:26
even if a small nation can only
51:28
contribute paper clips let him
51:29
contribute all they can to the
51:32
establishment of the space economy and
51:34
it would encourage international
51:37
cooperation to the point where it would
51:40
be the equivalent of a world government
51:43
world government has a bad press nobody
51:45
wants a world government but I say we
51:49
need a world government and I admit that
51:52
might be a good idea not not to call it
51:54
a world government I figure you can call
51:56
it anything you want you can call it
51:58
anarchism if you want you can call it
52:01
freedom and liberty if you want you can
52:03
call it a genuine cooperative spirit
52:07
amongst Earth's proud population if you
52:10
want just so long as it's really a world
52:13
government it's necessary you can't help
52:17
but as long as the world is divided up
52:19
into 150 separate regions each one of
52:21
which thinks each one of which thinks
52:23
it's God and that it's national security
52:26
comes first and everything else second
52:29
we're all gonna die so we got to get
52:32
I don't like having a now world
52:34
government I don't like any government
52:35
they all charge me taxes I hate it but
52:40
there's no way out you got over you look
52:43
I get letters from people saying yours
52:45
for less government what they really
52:47
mean is yours for Less centralized
52:49
government if Washington abdicates and
52:52
there's less government at the center it
52:55
means that the local bully-boy and the
52:57
block is the government and I would
53:00
rather have it in Washington the local
53:02
bully-boy knows where to find me
53:08
so there's the future I foresee as a
53:13
possible one energy from space space
53:17
fully exploited a nice computerized
53:19
automated civilization women's lib also
53:24
which I haven't discussed in this
53:26
particular speech but for very good
53:28
revolutions in education and automatic
53:32
end to racism because the earth cannot
53:35
can cannot continue under an appropriate
53:39
civilization as long as some people feel
53:41
rightly that they are discriminated
53:45
against and this is going to be a sort
53:48
of peaceful world a sort of world as I
53:51
see it which has accomplished its aims
53:54
and they're liable to be bored to death
53:57
I mean having saved them from all the
54:00
different kinds of deaths through
54:01
overpopulation through energy starvation
54:03
through pollution through internal
54:05
violence and terrorism through all this
54:07
you end up with everyone just yawning
54:10
themselves to death Plus after all
54:13
through all of history through all of
54:15
history men have been used human beings
54:18
have been used to living with risk and
54:20
danger etcetera etcetera all still
54:22
exists up there and in the end find new
54:26
place where for a period of time
54:28
population can expand where you can be a
54:31
pioneer where you can take your risks it
54:33
may be that the space settlers will be
54:36
the cutting edge of human exploration
54:38
that it is they who will explore the
54:41
outer solar system it is they will build
54:43
and take part in this great starships
54:46
that may someday leave the solar system
54:48
forever on their slow way towards
54:51
distant stars it is through them that we
54:54
may fall heir to the universe it is
54:56
through them that we will finally
54:59
outgrow the infancy of the human race
55:02
stuck as it is to the cradle of the
55:05
earth and through them we will finally
55:07
become adults and expand and spread out
55:11
into our proper home which is nothing
55:14
less than than the entire universe and
55:18
find other creatures intelligent enough
55:21
to be expanding on their own then I
55:24
suggest we will by that time discover
55:27
that there is such a thing as a sibling
55:30
hood of intelligence any intelligent
55:34
species that has reached the point where
55:37
it can expand beyond its own planetary
55:40
system must have defeated those or maybe
55:44
never had them those vile instincts
55:48
which led them to fight with each other
55:50
because if we can't defeat them
55:52
we'll never get out into space will all
55:54
die right here on earth if we get out
55:57
into space it's because we have learned
55:59
how to do something better than to
56:02
destroy our brother and sister and if we
56:05
do they do too and when we meet it will
56:08
be on an entirely new basis of humanity
56:12
in a general sense not referring to the
56:15
human species alone after all the vast
56:19
evolution of the universe from the very
56:21
beginning of its existence as a cosmic
56:26
egg or is a thin scattering of dust and
56:29
gas has been to increase the complexity
56:33
of its parts until some of it has grown
56:36
sufficiently complex to have a brain
56:38
sufficiently elevated to be able to look
56:40
at the universe and wonder what it is
56:43
and what it's like and how best to
56:46
cooperate with it to expand it is
56:49
different parts of the universe becoming
56:52
aware of itself and it doesn't matter
56:55
what the outward shape of the
56:58
self-awareness is only its function that
57:03
of self-awareness and when we can join
57:05
the Brotherhood of intelligence at last
57:08
we will know that the human species is
57:12
finally adult thank you very much
