Responding to this cynical take will quickly devolve into an argument about whether altruism is "real", so let's skip to the end where we agree that however this tendency evolved, people do in fact do things with no intrinsic motivation beyond making the world a better place.

Maybe this is a good use of AI for auto moderation. Save everyone time rehashing the same argument path for recognized arguments by providing the conclusion that the discussion is ultimately leading to. Seems like a good fit for a Black Mirror episode.

Humans are perfectly good at recognizing rehashed arguments without the need for AI. The difficulty is that the current crop of social media platforms focus on ephemeral discussion and provide poor tools for "linking" a discussion to an isomorphic one that happened earlier. The incentive structure is such that they would rather you go ahead and rehash the argument. Yay, engagement!
