I know for a fact that researchers in their early 20s change their mind quite a lot, and so a cure to aging would also mean more of that.
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. Iād guess that more neuroplasticity or neurogenesis is better than less, but I donāt think itās the whole problem. Youād need people to lose strong connections, to āforgetā more often.
Also, peopleās brains up until their mid 20s are still developing and pruning connections.

Iām not convinced there is actually that much of a difference between long-term crystallization of habits and natural aging. Iām not qualified to say this with any sort of confidence. Itās also worth being cautious about confidently predicting the effects of something like this in either direction.

George Church is over 60 and Iāve heard some people refer to him as a āchildā, given that he seems to not strongly identify with strongly held beliefs or connections (heās also not especially attached to a certain identity). I talked to himāhe cares more about regeneration/ārejuvenationāor maintaining the continuity of consciousness and the basic gist of his personality/āmode of being than about maintaining specific memories (regeneration/ārejuvenation research may ultimately come down to replacing old parts of your brain or identity with new untrained tissueāthis is where developmental biology/āSCRB becomes especially relevant). In fact, heās unironically bullish about anti-aging therapies coming in his lifetime

There are some scientists who roamed around and never really crystallized (famous examples being Freeman Dyson and Francis Crick)
