Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

by some of the top researchers who've been studying nuclear winter for a long time.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

And what they basically did was they combined climate models with food, agricultural models.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

So instead of just saying, yeah, you know, it gets really cold, blah, blah, blah, they figured out actually how many people would die in different countries.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

And it's pretty mind-blowing.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

So basically what happens is the thing that kills the most people is not the explosions, it's not the radioactivity, it's not the EMP mayhem, it's not the rampaging mobs foraging food.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

No, it's the fact that you get so much smoke coming up from the burning cities into the stratosphere that...

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

spreads around the earth from the jet streams.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

So in typical models, you get like 10 years or so where it's just crazy cold.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

And during the first year after the war and their models, the temperature drops in Nebraska and in the Ukraine, bread baskets, you know, by like 20 Celsius or so, if I remember.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

No, yeah, 20, 30 Celsius, depending on where you are.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

40 Celsius in some places, which is, you know, 40 Fahrenheit to 80 Fahrenheit colder than what it would normally be.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

So, you know, I'm not good at farming.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

But if it's snowing, if it drops below freezing pretty much most days in July, that's not good.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

So they worked out, they put this into their farming models.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

And what they found was really interesting.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

The countries that get the most hard hit are the ones in the Northern Hemisphere,

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

So in the US, and one model, they had about 99% of all Americans starving to death.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

In Russia and China and Europe, also about 99%, 98% starving to death.

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

So you might be like, oh, it's kind of poetic justice that both the Russians and the Americans

Lex Fridman Podcast
#371 โ€“ Max Tegmark: The Case for Halting AI Development

99% of them have to pay for it because it was their bombs that did it.
