AI LLM systems, i.e. perplexity.ai, are very good at tutoring someone about how something works, i.e. advanced math, and when done in a loop can be very useful at tutoring, better than youtube videos I've seen on the same subject. The one thing I will usually request in (in the case of math), is to suffix the prompt with "explain this in terms a 9th grader would understand", and this is good enough to explain something in simpler terms with various breakdowns that can be understood by anyone to tutor yourself in alot of subjects using this method. This can be applied to programming, auto repair, construction, almost any subject at this point.
