Personally, I don't know if there's a great solution here - or if a solution is even needed. Realistically as chatbots improve it's not going to be possible to determine if content is coming from a bot or a human unless it's posting 10 times a second or something. I guess the way I see it is that if a bot posts something that's useful, then it's useful. The only issue I see is spam and low quality content. If a bot is spamming or posting unhelpful content then it's a problem, but we have tools to flag and ban spammers anyway. Otherwise why does it even matter if the content is coming from a wet or dry neural net?
