I'm making an assumption here, but I think paulg is implying that "learning LLMs" today is like the equivalent of "learning computers" in the earlier days. We could even divide civilization into two eras: Before Transformers (BT) and After Transformers (AT).

I watch Khan Academy videos because they explain topics like mathematics in an easy-to-understand way. But it's just one tool in a student's arsenal. Khan Academy is by no means the one-stop-shop for education and should not stop learners from inquiring, constructing, expressing, and communicating as part of their learning journey. I hoped that the author would at least make that distinction a bit more in their article because it seemed a little unnecessarily critical. I _think_ the article makes the assumption that most students are just passively watching videos and _are_ using Khan Academy as the one-stop-shop and that the site (and Khan) are missing out on an opportunity to provide a better experience that is more in line with John Dewey's principles of learning.
