How do you know these are bots and not Redditors? There's an HN sub on Reddit, and one of the hallmarks of Reddit are the 'mic drop' big pivotal one liner comments that get upvoted or cause lots of replies or engagement.
But I do feel, to reply to you, that crypto was a lot more critically received on HN than AI is right now. We're too busy debating humanity's end rather than if this crap actually works.
For those of us who actually work with technology (not product managers, executives or salespeople, this stuff doesn't work well at scale. It might in a research department at Google or a hedge fund, less so in the messy corporate world.
