Fuck AI

Is your premise even correct? I don't have any data indicating that leftists are anti-AI. Do you?

Also, I'm not sure what you mean by anti-AI. Pointing out that it is snake oil is a factual claim. In other words, if AI is a label that's mostly devoid of meaning, then attacking it is actually attacking the sleazy opportunistic salespeople, and not necessarily the underlying tech (when it is clearly defined, which is rare). Of course one could oppose both.

Which is to say, many leftists are anti-billionaire, and many billionaires are riding the AI bubble. But you already know that, so probably that's not what you're asking.
