I believe Stack Overflow and Quora were screwed because chatbot interfaces became the new entrypoint. _If_ Instagram/TikTok/YouTube manage to stay the place people go habitually, then I think they will benefit, not be harmed. But there are probably many ways to step wrong here. There is a bit of an innovators dilemma for the platforms that currently relies on human produced content. If I were them, I would fund 2-3 new/separate efforts to be able to experiment while not immediately killing the current golden goose.
