I think he is wrong when he says AI is useless. I agree that it's far from being as useful as assholes like Amodei claim it is, but it clearly has use cases.
Then again, that is the weak part of Zitron's argument, and laughably the only thing his critics like to engage.
When he brings up the bonkers economics of AI, and how absolutely unsustainable it is, his arguments are very solid. I am still to see one good counter to him there. It's not like he lacks haters who could try.
