uh of the entire physical reality around you is also tracking the details of your hands in order to use that for like gesture recognition this kind of stuff yeah we've been able to get way further on hand recognition in a shorter period of time than i expected so that's been pretty cool i don't know did you see the the demo um experience that we built around um piano like yeah the piano learning to play piano yeah it's incredible

Well, there's what you can do with avatars overall in terms of superimposing digital objects on the physical world.

And then there's kind of psychologically, what does having photorealistic do?

So I think we're moving towards a world where

We're going to have something that looks like normal glasses where you can just see the physical world, but you also see holograms.

And in that world, I think that they're going to be not too far off.

Maybe by the end of this decade, we'll be living in a world where there are kind of as many holograms when you walk into a room as there are physical objects.

And it really raises this interesting question about what are...

You know, a lot of people have this phrase where they call the physical world the real world.

And I kind of think increasingly, you know, the physical world is super important, but I actually think the real world is the combination of the physical world and the digital worlds coming together.

But until this technology...

they were sort of separate, right?

It's like you access the digital world through a screen, right?

And maybe it's a small screen that you carry around, or it's a bigger screen where you sit down at your desk and strap in for a long session, but they're kind of fundamentally divorced and disconnected.

And I think part of what this technology is gonna do is bring those together into a single coherent experience of what the modern real world is, which is it's gotta be physical because we're physical beings.

So the physical world is always going to be super important, but, but increasingly, I think a lot of the things that we kind of think of, um, can be digital holograms.

I mean, any screen that you have can be a hologram, um, you know, any media, um, in any book art, um, you know, it can basically be just as effective as a hologram as a physical object, any game, um, that you're playing a board game or, um, or any kind of physical game cards, um,

You know, ping pong, things like that.

They're often a lot better as holograms because you could just kind of snap your fingers and instantiate them and have them show up.

You know, it's like you have a ping pong table show up in your living room, but then you can snap your fingers and have it be gone.
