It doesn't have to be used that way, though. I wouldn't disagree that it mostly is used that way, but it can just as easily be used to teach. My wife has proven that well. AI has been the best development ever for her because it can custom tailor the lesson/task to be hyper relevant to exactly what she is trying to do.

Personally I've always preferred a great book to blogs/tutorials/etc, and even still I'd reach for a book if I had the chance on a new programming language or anything. But not everyone learns well that way, and I accept that.
