Oh, I definitely agree. I appreciate the perspective. The Feynman lectures are great at giving an intuition and perhaps a general framework for thought.

What they don’t give you are tools; like you say, you had to learn them in other places before really appreciating the lecture.

But those lectures do seem to leave many people with the feeling they also got the tools and not just the gist.

They are enjoyable. They are informative. But they are not at a textbook level, even though they leave the impression that they are.
