It really is sad indeed. You die a hero (stop posting videos once you’ve exhausted your expertise) or live long enough to become a villain indeed.

I don't follow Hossenfelder that closely, so I haven't seen any of her videos on economics. I have seen her walk back some of her misunderstanding around global warming, however.

Celebrating someone's achievements in a specific domain is not giving them carte blanche across the board. Personally, I think it more productive to celebrate someone's successes while lamenting their failures. If one thinks that mediocrity is the norm (which it is, by definition), then transcending it, even briefly, it something to celebrate and use as inspiration, even while acknowledging that all individuals have flaws (to some degree).
