Difference between "oneliness" and "loneliness" is crucial. I was little astonished when Lex Fridman told us that he does not have "Inner Voice" commenting all his doings.

I have sometimes spent 6 months alone in wilderness and eventually the Inner Voice kicks in. It seems to be a mechanism to maintain sanity. Upon returning to civilization the Voice soon disappears.

In my case the Voice is a film director, mostly Werner Herzog, who might say, "now the subject has finally lost his marbles and does not make bear-proof stash for his food".
