Generic questions usually don't have a good answer. It's like asking whether it is okay to learn from books. Depends on the book, and how you use it. There are certainly some horrible books out there. There are also good books. There are books that someone read once and expected to become a guru, when you actually had to do all the exercises.

Learning from AI requires certain skills. You need to ask the right kind of questions. You should use AI together with other sources of knowledge, not as a replacement for them. For example, you can read a book, and when you have an additional question, you can ask the AI. Or you can ask the AI first to provide you a high-level summary of a few books, so that you can choose the right one to read. You can try to solve a problem on your own, and afterwards ask the AI how it would do it. You can ask AI to comment on your solution, or to modify it.

It is not possible to learn while remaining completely passive. Ultimately, learning is an activity of your brain in response to the inputs you get; if you do no activity, there is no learning. But AI can give you the inputs you want, quickly. (Much faster than a search engine, which was a huge improvement over searching various catalogs, which were a huge improvement over clicking random links and hoping to arrive at something relevant.)

Maybe one day there will also be an AI tutor for lazy people, where you won't even have to ask the right questions, because it will be programmed to think for you. (It might contain a loop of asking itself what is the right question you should ask at this moment, and then giving you both the question and the answer.) I don't see a reason why such thing couldn't exist in principle, but I also expect the first few implementations to contain some big flaws.
