What's interesting about that theory is that Descartes was at least one of the first people to talk about this thing. How do I know I'm not brain in a vat being stimulated by scientists so that I think I'm sitting in this sunny living room talking with Jordan and so on? And people have worked on better and better versions of this.

And obviously, in the modern computer era, this became, how do I know I'm not a computer simulation? Well, what's been so weird to watch just over the last decade, really, is... how extraordinary things are becoming. For example, with generative AI, people are using this in VR now to create whole VR worlds instantly. Like, hey, I want a 15th century whatever with a castle.

And this just gets created the same way you would create an image, but a whole 3D VR world. And we're just in 2025. I mean, just imagine what things are going to be in 2045 or something. So the point is, it becomes more and more plausible to say, God, we know we can make extraordinary simulations. Why not? And all it requires is imagining that maybe...

Just imagine our civilization a thousand years from now, they might be running these sims. And of course, this could be recursive all the way down.

So do you remember the website called Second Life? Yeah, of course. Philip Rosedale, a friend, he's the guy who started that. Wow. And for those who don't remember Second Life, it's just you get to be an avatar in this little computer world. You walk around, you talk to other avatars, and you can talk to them. First, I met a couple that had met in Second Life, and they were married to one another.

That's how they met each other. But it turns out that's not uncommon. Here's the thing. Technology has moved way on beyond Second Life. But there's still about a million people that use Second Life every day.

And these people often, not always, but quite often are people who, for example, are in wheelchairs or have other physical ailments, and they can be in Second Life and be avatars and live this other kind of life, which is precisely what you're describing. It's exactly the kind of thing.
