Fuck AI

Your AI detector is busted, bud.

Just because it would be convenient for what you already believe doesn't make something true.

It's wild that their post doesn't read like AI, is broadly more critical of AI than not, and yet because it doesn't blanket condemn AI as pure irredeemable sin - people just assume it's AI written? We've got to be careful not to let AI become this ultimate unfalsifiable scapegoat, where any time someone puts forward a line of reasoning that makes me uncomfortable, I can just say "oh wait, I know, it must be AI!" and stop thinking about it. It's so dangerous for people to have quick general purpose ways out of cognitive dissonance like that, because it prevents people from moving from wrong positions to right ones.

In addition, just because information is AI generated does not make it false. If an AI tells me the sky is blue I'm not going to start believing the sky is actually green. But the same goes for for knowledge I'm not already sure of. An AI is capable of generating good or bad arguments for a position, and if it really is just plagiarizing as you say, then whatever arguments it regurgitates would have been initially put forth by a human and worthy of your consideration by the "debate us like a real human" standard you put forth, anyways. So even if their post was generated by AI, the theoretical problem with that, according to you, is that it would be nonsense - and if that's the case, you should be able to refute the content of the argument directly rather than criticizing the source.
