I would argue it has gotten way better. Depending on the subject it can be really helpful and some tools even have a learning mode built in now that can generate questions and tests. They are often way too easy to solve but it does not demotivate i guess.
It has always gotten better, just like how self-driving cars have gotten better, and how the case for bitcoin is always getting stronger.
Many people have stopped believing this lie. Yes AI has gotten better by some metric which AI companies are pushing. It has not gotten good enough to be a qualified teacher, and it never will.
