Your vouching for centralization of knowledge, and even understanding, which I think is a very bad idea. It’s not like the rest of us are becoming specialized at something else - knowledge, in the broad sense, is the foundation of all skills. Without it we have nothing to contribute
You are free to learn whatever you want to. I'm saying I would greatly prefer talking to an AI model that was trained by an expert or the guy who created it, or trained via an RL environment that guarantees its correctness (where possible), and not take a chance on whatever or whoever happens to be teaching the subject that day. My experiences are my own, but I have repeatedly encountered people time and time again who profess to know how something works or have a deep understanding of something and it turns out that they, in fact, do not. It turns out its very easy to convince people you are knowledgeable about something who don't know anything about the subject.
