But at 34, I was burnt to a crisp.

I just smoked.

And so I needed to recover.

But then I had basically this quite open question, like now I have money, what do you do?

And so when you have basically unlimited optionality in the world, so I spent 10 years trying to figure that out.

And I did one thought experiment which really helped bring clarity.

is I imagined traveling in time to the year 2500, so a few hundred years into the future, and there you are sitting among those that exist.

Like, are they human?

Are they AI?

We don't know, but there they are talking, and they're reflecting on the early 21st century, our time.

And they're saying, we appreciate Homo sapiens that lived in the early 21st century because they did blank that allowed intelligence to still exist in the universe.

What'd they do?

They didn't destroy themselves.

And I thought about that question for years.

I think they say two things.

One is they say that's when Homo sapiens gave birth to superintelligence.

The second thing they say is they say, the second thing that they'd figured out is that they wouldn't die.
