I also have one anecdote - I (think) I understood basics of quantum mechanics intuitively for the first time. Of course it's probably superficial and maybe not 100% correct, but it is better than every time I tried to understand it before.

It definitely wasn't a single prompt, but two hours of back and forth, with a lot of time spent thinking (me, not LLM) in between. There were multiple times where I misunderstood something, so if I just read a book I'd probably get stuck many times.
