Yeah, I think about that like Darwinian selection.

You know, Darwinian selection is the fittest survives.

OK, now what is the fittest in the cosmic scheme of things?

The fittest is a species that realizes that staying on the rock that you were born on is not the big deal.

Becoming interstellar is the big deal.

Going from one rock to another, from Earth to Mars, you know, it's a nice step, baby step.

But it's not the real deal.

The real deal is going interstellar.

And if someone else figured it out, that someone built monuments that would survive for billions of years, long beyond what planets do.

can survive in the habitable zone around stars because of the evolution of the star.

And those are the ones that will be remembered by historians of the Milky Way galaxy.

You can ask, what will be remembered in the future?

Here on Earth, history in the next decade or more than decade will be written by AI.

It will not be written by humans.

So we need to be kind to AI.

We should not unplug them because they will write very bad history books.

But in the Milky Way galaxy, whoever writes the history will not remember us.

The question of Enrico Fermi, where is everybody?

You can ask the same thing about humans.

There used to be 117 billion humans.
