Gary Marcus always, always says AI doesn't actually work - it's his whole thing. If he's posted a correct argument it's a coincidence. I remember seeing him claim real long-time AI researchers like David Chapman (who's a critic himself) were wrong anytime they say anything positive.

(em-dash avoided to look less AI)

Of course, the main issue with the field is the critics /should/ be correct. Like, LLMs shouldn't work and nobody knows why they work. But they do anyway.

So you end up with critics complaining it's "just a parrot" and then patting themselves on the back, as if inventing a parrot isn't supposed to be impressive somehow.
