  1. We don't have recordings of Feynman's professional lectures for all I know.

  2.  @MegaAvinator  Good guess. K-12 + undergrad equals roughly 15,000 hours of learning. Maybe a little over 20,000 for those who are extremely studious. :-) You know what, though? An AI can be trained to know a hundred times, if not a thousand times more in a month or so. That's just an LLM that can't reason with that knowledge, yet, of course... but just imagine somebody manages to connect that LLM to an actual reasoning model. Now you got a problem. ;-)

  3.  @sheldonrego6121  Yes, it needs undergrad physics, which is two years, three at most.
