It doesn't mean he's wrong! it means he's out of touch and doing the propaganda work of capital for free much like many other self-employed/business owning/petit-borgeois people who think they're on the side of capital.
It also means that his praise for and indeed positive experience with this "tool" is largely irrelevant to the broader social/economic discourse surrounding so called AI.
Blind hatred for AI as a technology is inherantly reactionary, but that doesn't mean that the implementation of the technology today isn't problematic in many ways.
