Quora already has a "prompt generator" that writes questions that are at least as good as the human beings. And much better than the human beings in the Quora Partners Program, who were paid to ask questions (and therefore preferred quantity over quality).

I bet an AI could also answer those questions, too, at least as well as the average human. They won't do that (at least not yet) since their goal is to show ads to humans rather than answer questions -- and they've found that people come to do "recreational typing" (and will see ads in the process).

The AI won't replace the humans who are genuinely curious, but it has already replaced the ones who were being paid to ask questions.
