It’s unfortunate - he’s an author, it would have been fine to stick with an authors perspective that LLMs can’t write (which is true), as well as the copyright stuff (which I don’t agree with but he certainly has standing to give an opinion on).
But he’s made the error of trying to come at it from a technical perspective, when he clearly knows nothing about that side of things, which discredits the rest.
How does a tiny error, in an aside and unrelated to the greater point, made at near the end discredit the rest of it?

Huh? That quote appears to be the entirety of the "technical perspective" of the post and is an aside from his larger points that you have blessed as "fine". Literally nothing in the rest of the post relies on that incorrect statement.
Let me quibble with what is discredited here, given the entirety of your point is built upon an error.
