How about the danger that AI itself becomes insane?

On the HN "new" page as I write this: "Google and Microsoft’s chatbots are already citing one another's misinformation". As AIs produce more and more content, one danger is that they feed back on each other, with AIs training on more and more AI-generated content, and the connection with reality becomes more and more diluted. I don't think that's going to produce some new kind of wisdom; I think it's going to produce raving lunacy.
