As I wrote here, I think this could be due (in part) to biases accumulated by being in a field (and being alive) longer, not necessarily (just) brain aging. I’d guess that more neuroplasticity or neurogenesis is better than less, but I don’t think it’s the whole problem. You’d need people to lose strong connections, to “forget” more often.
George Church is over 60 and I’ve heard some people refer to him as a “child”, given that he seems to not strongly identify with strongly held beliefs or connections (he’s also not especially attached to a certain identity). I talked to him—he cares more about regeneration/rejuvenation—or maintaining the continuity of consciousness and the basic gist of his personality/mode of being than about maintaining specific memories (regeneration/rejuvenation research may ultimately come down to replacing old parts of your brain or identity with new untrained tissue—this is where developmental biology/SCRB becomes especially relevant). In fact, he’s unironically bullish about anti-aging therapies coming in his lifetime
