Where I find it incredible - learning new things, I recently started flutter/dart dev - I just ask Claude to tell me about the bits, or explaining things to me, it's truly revolutionary imho, I'm building things in flutter after a week without reading a book or manual. It's like a talking encyclopaedia, or having an expert on tap, do many people use it like this? or am I just out of the loop, I always think of Star Trek when I'm doing it. I architected / designed a new system by asking Claude for alternatives and it gave me an option I'd never considered to a problem, it's amazing for this, after all it's read all the books and manuals in the world, it's just a matter of asking the right questions.

From the about the authors in the OP's link "Feynman was a remarkably effective educator. Of all his numerous awards, he was especially proud of the Oersted Medal for Teaching, which he won in 1972.". He probably didn't do a lot of the stuff he popularised, but that was what he did, it is a skill taking abstract stuff and making it coherent. I know when I did physics (in the 90's) many swore by his books, particularly for quantum, it was a bit of a secret we'd have these incomprehensible books on quantum, and someone would say - have you seen "The Feynman lectures", they are good, I wish we had the videos available at the time.

This probably has something to do with it.

This is what I've noticed about most LLM generated code, its about the quality of an undergrad, and I think there's a good reason for this - most of the code its been trained on is of undergrad quality. Stack overflow questions, a lot of undergrad open source projects, there are some professional quality open source projects (eg SqlLite) but they are outweighed by the mass of other code. Also things like Sqllite don't compare to things like Oracle or Sql Server which are proprietary.

Shop bread and tomatoes though can be manufactured without any thought of who makes them, though they can be reliably manufactured without someone guiding an LLM which is perhaps where the analogy falls down, and we always want them to be the same, but software is different in every form.
