i've heard it described that evil is that which believes itself to be good without exception. i think i'm starting to agree...
As far as I understand, there is plenty of research there in disciplines raging from social studies through psychology to game theory and economics, as well as informal simulations, that strongly suggest that human interactions are positive to participants pretty much if and only if those interactions are repeated, which realistically only occurs if participants are circumstantially close already - same neighborhood, same job, family, friends, same school, etc.
One-off interactions are almost invariably toxic with at least one of the participants getting cheated, bullied, or otherwise harmed.
So the whole premise of connecting people unconditionally, including anonymously, automatically, and from opposite sides of the world is inherently broken and doomed to do a lot of damage.
So even Meta's self proclaimed mission is damaging to society if followed, what could possibly at that point be expected from what they actually do, given the combination of basic facts that the primary purpose of any business is to make money, Meta's specific notoriously evident disregard towards ethics, their position as an advertisement business and entertainment provider, being deep into enshitification and market saturation, and of course actual honest mistakes to boot.
> One-off interactions are almost invariably toxic
I think these claims are too strong. I can believe that there's less incentive to treat people well when you don't expect to repeat interactions.
To give a mundane counter-example: last week I had a flight where I chatted on-and-off with the person next to me. I had zero expectations of repeat interactions with them following the flight, and it was still a friendly and courteous exchange, on both sides.
