The article you link says not a lot of criticisms with very many words, and the AI prose gets much worse towards the end, seemingly when the author also gave up on reading it. I am disappointing in the plagiarism though, especially of Ryan Smith.
I am much more interested in what you think of the site though vs your own experiences running a GPU cloud. I've seen your comments on it for a long time, it's super interesting. So if you think their takes are mostly bunk I'd consider it way more than this hot aisle guy.
