Thanks for the in depth writeup, this is all super interesting, and lo and behold it sounds like the answer to what I was poking at was "it depends" and "there is nuance", which is honestly super neat. Just more fuel for the fire of "the human brain is fantastically complex and we know so little about it", the fact that the two of us could have such different experiences and mechanisms, that ultimately serve similar purposes; move a human being through their lives, while keeping them alive and "well".
