It’s not about intelligence, it’s about patterns. The bigger LLMs can already mimic the smartest individuals fairly well.

Lemmy has a small userbase that has a high percent of humans vs bots, but a lot of those people tend to be whackos. Reddit has a huge user base with way more bots and whakcos (both by percentage and raw numbers), but also more normal humans. So there’s a tradeoff there in which platform you use I suppose.
