https://en.wikipedia.org/wiki/Planck%27s_principle "Science progresses one funeral at a time" basically says that people, even very smart people, can't unlearn, so the only way humanity as a whole can unlearn is via people dying off. Maybe it's a problem we should give more attention before tackling aging.

I think this is rather lopsided statement of the idea. It's not the only way; but it's one of the ways.
