#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

But again, just to be clear, these are mechanisms of the physical interface.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

What we haven't gotten is a mature theory of how they map onto the space.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

That's just like just beginning.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

But I'll tell you what the physical side of things look like.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

The first one has to do with stress propagation.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

Okay.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

So imagine that, um, you've got a bunch of cells and there's a cell down here that needs to be up there.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

Okay.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

All of these cells are exactly where they need to go.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

So they're happy.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

Their stress is low.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

This cell, now, now let's imagine stress.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

Stress is basically a, uh, uh, uh,

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

It's a physical implementation of the error function.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

It's basically the amount of stress is basically the delta between where you are now and where you need to be.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

Not necessarily in physical position.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

This could be an anatomical space and physiological space and in transcriptional space, whatever, right?

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

It's just the delta from your set point.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

So you're stressed out, but these guys are happy.

Lex Fridman Podcast
#486 โ€“ Michael Levin: Hidden Reality of Alien Intelligence & Biological Life

They're not moving.
