Here's a fascinating (at least to me) series of lectures by one of my heroes - Richard Feynman. These are all about an hour long, and I was enjoying his engaging talks about diverse topics. For example, below. You get a flash at the beginning that I missed. But at the bottom it is Feynman Reborn, an AI Feynman, along with unmistakably his voice. There is a list of publications at the bottom (for example the Feynman Lectures on Physics). There is a series of these, and the only real hint that something is up is if you look at the background. I think that the authors of the AI Feynman left a really weird background to give a sense of the unreality of the superb AI Feynman.

ew.

Yes I know. But it is nonetheless exceptionally persuasive.

There is a time oddity though. The AI Feynman talks about dark matter (which was around as a measured thing well before he died) and Dark Energy, which postdated his death.

I'd clearly forgotten that Feynman died aged 69 (from cancer). Reputedly his last words were "This dying is boring"
