#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

You can put electrodes in there and you can put weird nanomaterials.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

It still works.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

It's it's this is that problem solving action, right?

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

It's able to do what it needs to do, even when circumstances change.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

That is, you know, the hallmark of intelligence, right?

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

William James defined intelligence as the ability to get to the same goal by different means.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

That's this.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

You get to the same goal by completely different means.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

And so so so why am I bringing this up is just to say that, yeah, it's important for the cells to do the right stuff, but they have incredible tolerances for things not being what you expect, right?

and to still get their job done.

So if you're, you know, all of these things are not hardwired.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

There are organisms that might be hardwired.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

For example, the nematode C. elegans.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

In that organism, every cell is numbered, meaning that every C. elegans has exactly the same number of cells as every other C. elegans.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

They're all in the same place.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

They all divide.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

There's literally a map of how it works.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

In that sort of system, it's much more cookie cutter.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

But most organisms are incredibly plastic in that way.

Lex Fridman Podcast
#325 โ€“ Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots

Right, very hard, to the point where I often, just imagine, I sometimes ask my students to do this thought experiment.
