>Better then textbooks? Better then an online course? Better then watching youtube videos from Khan academy, or just better then nothing at all as described some metrics which the AI companies came up with them selves?

The value of all of these self-learning routes has increased enormously due to existence of AI assistants. At least the way I do it now, I get the initial structure for a subject from YouTube/Udemy/textbooks and then fill out my personal comprehension gaps with the help of AI. You can even point AI to a specific material you're trying to grasp and usually it will rephrase a point you failed to get in a simpler language.

Previously, you'd need some trained person to explain to you something that led you to hit a roadblock. Now, the level of understanding you get easily beats most of the tutors in public schools or community colleges.

This is a lie and most of us know it. AI companies have been lying and lying and lying and lying. If you believe this then the AI companies have successfully lied to you and are making you pay money for an inferior product. If this weren’t a lie then the AI companies should have the research to prove it, they have not, because it is not true. AI does not help anybody learn anything better then using traditional methods.
