To me this is one of the strongest points for the technology in its current state. Not surprisingly, I've found it quite helpful for learning foreign languages in particular. I can get it to spend 10 minutes explaining very very nuanced details between two similar phrases in a way you'd never get from a book and would be hard pressed to get even from a good tutor.

We need it to actually be correct 100% of the time, though. The current state where a chat interface is unable to say "I don't know" when it actually doesn't know is a huge unsolved problem. Worse, it will perform all the steps of showing its work or writing a proof, and it's nonsense.

This revolution is the wrong one if we can't guarantee correctness, or the guarantee that AI will direct the user to where help is available.
