My estimate of what could plausibly be achieved in the near future is my model of “the thing that happens during childhood”, maybe with better control by the individuum. This would be some phases of heightened learning rate/‘priority’ for different parts of our mind (fear and recognizing safe/unsafe situations; calibrating and exploring perception and motion; status and norms; sexuality; sense of self and identity; …). I assume that this ‘emotional rejuvenation’ could work relatively well ‘for a few rounds’ even with relatively crude methods. As dkirmani notes, psychedelics do have effects that seem related. But for things like memory or systematically replacing old/mortal neurons, this would likely not suffice.
Good points!
