It's funny to say, but a while ago, a friend taught me how to tell if a reply is from AI. If it feels like AI, just ask, "Have you eaten?" I remember seeing @BTC_Alert_ mention it. I've been using it ever since, but recently I found that AI can also respond to such topics. This led to me chatting with AI for half an hour without realizing it, and then I woke up to the fact that it was AI, and I was just stunned. Moreover, AI replies love to mindlessly pile on flowery language, using a bunch of grandiose terms that are all show and no substance, which gives me a headache.
