Not in form of quiz, but yes, when I'm wondering about something, nowadays I'll just chat about it with AI. The contrast to trying to learn the same thing with googling is massive; partially this is because AIs truly are so great, but partially because the baseline (Google) sucks so colossally.
In fact, it's interesting how Googling is not much more effective, or at all, than actually going to a library (travel included), finding the right physical books, and reading through them until you find what you need. Expect to spend tens of hours to build some basic-level understanding either way. Classic Google (web pages) human-slop/noise is such a huge problem, and Google always sucked filtering high-quality content from the large mass of human slop.
With AI, this is different. You can build the knowledge and ask the right questions within an hour of chat. And unlike on forums like this (and this is one of the best - most are much worse), where people misunderstand you if you don't write a perfect question, and even if you do, many just answer even if they didn't understand the question, creating human slop, AI seems to get the gist of your question even from a misformed prompt.
