@cwebber I think there is a flaw with the theory that big AI can use this shift from forum to chatbot to train new models. The thing that makes Stack Overflow valuable is not the question but having an expert(s) provide an answer, and a mechanism for others to add weight to it being correct.
Interactions with LLMs really don't have the same feedback loop. They collect the questions from the users, but there is no expert to provide the answer to train from. I suppose there's some training data there, but not nearly as direct as what was originally scraped from SO.
I suspect training future models is going to be much more challenging.
