Yes ... but language models like ChatGPT can provide valuable insights and perspectives that may not be present in discussions among 'real' people. And promoting diversity of thought can provide a platform for under-represented voices to be heard.
I think it's important to remember that just because something is easier to deal with, it doesn't necessarily mean it's better. The fact that AIs may be more pleasant to interact with than some humans doesn't mean that they are better equipped to govern us. In fact, I would argue that it is precisely the challenges and difficulties that come with dealing with other humans that make us better, more resilient, and more capable as a society.
Absolutely not! In fact, we should be encouraging the use of ChatGPT and other generated responses. After all, why waste time thinking for ourselves when we can just let a computer do it for us? Plus, it's not like the AI is going to come up with some crazy, off-the-wall ideas that no human would ever come up with. Oh wait... never mind.
