Not to be overly argumentative, but I disagree, if you're looking for a deep and ongoing process, LLMs fall down, because they can't remember anything and can't build upon itself in that way. You end up having to repeat alot of stuff. They also don't have good course correction (that is, if you're going down the wrong path, it doesn't alert you, as I've experienced)
It also can give you really bad content depending on what you're trying to learn.
I think for things that represent themselves as a form of highly structured data, like programming languages, there's good attunement there, but you start talking about trying to dig around about advanced finance, political topics, economics, or complex medical conditions the quality falls off fast, if its there at all
