I'd totally pay for that (I'm serious).
"Man kills wife in fit of rage, throwing knife at virtual Gordan Ramsey"
- Says "he didn't see her behind the Gordan Ramsey avatar"Sounds very different without one. (!)
But that is not what you'd be getting. You can very well listen to Feynman's pre-recorded lectures on YouTube today, and that's the best than can be done. Listening to the same clip being played while some image of him is projected on your glasses to make it look like he's in your living room will not improve the experience.
The closest I've seen is tech that would put his face and voice over the answers that come from chat GPT. Again, with no respect to the late professor, but his appearance is again the least interesting part "talk with Rchiard Feynman" is his appearance and voice. If I could get his help on some of my research, I wouldn't care if he looked like a blob fish and had the voice of Foghorn Leghorn. On the other hand, if I'm just getting ChatGPT answers, then there's no reason not to just make it look like the Crypt Keeper.
We got that way back when god invented the book. Or I could prop my phone up against the back of the counter and have a little youtube in my field of view.
That's a feature? You can do that with a real ping pong ball... I'd love to not have to do it...
