Once somebody creates an AI that doesn't articulate as well as ChatGPT but imitates humans better, anonymous online discussion is dead almost instantly.
How can you ever guarantee that you are not arguing with a bot that will not get tired, answer almost instantly, and will gaslight you into anything it wants you to believe?
You can abort arguing with it at any time, sure, but is this a satisfying experience? No, it will be incredibly frustrating getting duped like this over and over again.
