If you google "ray dalio 1980" you'll see he's talked about that being his biggest mistake and massive learning opportunity [1, 2, 3]. He even dedicated a chapter to it in his book (chapter 3) [4]. It's sort of hard to fault someone for being wrong 40 years ago and think they have nothing new to contribute.
Suspect we'd all be completely screwed if we were wrong, never learned from it, and just continued on. No idea if he's right or wrong but guess time will tell. What you're implying here though, that because someone was wrong at a point in time, learned from it, evolved and changed their way of thinking, then think that all their future stuff is tainted somehow, seems pretty strange.
I'm not impressed with his story about what he learned from it. He basically says he learned that sometimes he can be wrong. No indication of whether he's learned when he's more likely to be wrong or right.
If you must simp for billionaires, Jim Simons, Bill Gates, and the Collison brothers are somewhat more interesting people IMO.
Since you mentioned him, Jim Simons has a really good interview too and it was pretty cool to hear his story [1]. Worth a watch if you haven't seen it and are into RenTec.
