At the end of the day you are basically typing prompts and reading answers by the AI, you do not know for 100% certain that they are correct so you would try to somewhat double-check their facts. Maybe you don't, regardless you are in essence tricking yourself into reading an interactive book guided by your prompts. You sure as hell won't become a professional at some domain by just reading this one interactive book. Try asking how to create some sort of vaccine and unless you specialize in that you will be quickly overwhelmed by the seemingly random terms the AI will spit out.
In my view these latest AIs will probably replace how we search for things in internet or heavily improve existing methods. It can already do that for you, simply ask the right questions, you can even set how it should roleplay as (e.g. Socratic style would be great for learning new things).
