The problem with trusting AI to learn a complex subject, which I've tried multiple times, is it will always at some point confidently give you the wrong explanation for something important and you will have no way to detect it. Its quite frustrating and that realization might not come for hours or days and you've built lots of false mental models that can be hard to untangle.

You have to do it along with some sort of ground truth, like a book, and you have to be able to understand that book in order to be able to see that bad advice immediately.

Alas, there are no shortcuts in life. You still need to very eagerly read and understand the source materials you're studying as you would have before AI and to the extent which AI is helpful for that is debatable. Your brain still has to do the thinking.

I agree with the sentiment of mixing up sources. However there are not really many textbooks that rise to the level of "ground truth". Plenty of times that books give wrong explanations as well.
