Stack Overflow would still have a vibrant community if it weren't for the toxic community.

Imagine a non-toxic Stack Overflow replacement that operated as an LLM + Wiki (CC-licensed) with a community to curate it. That seems like the sublime optimal solution that combines both AI and expertise. Use LLMs to get public-facing answers, and the community can fix things up.

No over-moderation for "duplicates" or other SO heavy-handed moderation memes.

Someone could ask a question, an LLM could take a first stab at an answer. The author could correct it or ask further questions, and then the community could fill in when it goes off the rails or can't answer.

You would be able to see which questions were too long-tail or difficult for the AI to answer, and humans could jump in to patch things up. This could be gamified with points.

This would serve as fantastic LLM training material for local LLMs. The authors of the site could put in a clause saying that "training is allowed as long as you publish your weights + model".

Someone please build this.

Edit: Removed "LLMs did not kill Stack Overflow." first sentence as suggested. Perhaps that wasn't entirely accurate, and the rest of the argument stands better on its own legs.
