This. Upthread commenters have suggested that Carl Sagan and Jim al-Khalili are comparable to Feynman as explainers of physics. Sagan was good at communicating a sense of wide-eyed awe; al-Khalili can tell a story well. But they both stay well clear of really hard stuff in their popular expositions. Feynman, on the other hand, didn't seem to have a sense that there was any "really hard stuff". Fools rush in where angels fear to tread (I don't mean to suggest that Feyman was stupid, rather that he was a great joker).
