His unemotionality. The way he speaks formally. His precise mannerisms. The way he always seems to be putting on a facade, like he's an alien pretending to be human.
I don't think he was intended to come across as autistic, he just vaguely seems like it.
Personally I treat my windows pc as a gaming console. I play games on it and nothing else. Then it becomes a non issue: so what if they track my gaming activity?
I think his idea was to reduce visibility of harmful content (like exclude it from the algorithm, or maybe just penalize it heavily) without fully banning it.
I suppose downvotes are also a solution (up to a point - doesn't work unless there is a strong enough consensus).
But even if these don't work it doesn't mean censorship is the only solution. Just because we don't have a good idea doesn't mean nobody will.
Radication and disinformation are serious problems and some censorship is better than nothing - but still seems like there has to be a better way.
Did you believe otherwise growing up?
