> What I’m trying to say is that what they’re suggesting doesn’t seem completely insane so the retort “You’re the groupthink” becomes an unfalsifiable statement thrown at anybody who’s “anti-AI” instead of engaging with their arguments.

I can't engage with his arguments, because he didn't present any. He's openly saying he doubts the provenance of any comment that is "minimizing the dangers if (sic) AI".

As for your expanding on why - you do realize that everything you said could apply to the other side: Bots can be set up to post lots of AI doom comments. What would you think if I went and posted "Every time I see a dystopic comment about AI, I wonder whether it's part of an AI swarm."
