/shrug. The guy can't keep from popping off with obviously false statements about things he knows nothing about. What exactly do you want me to say? Yes, he's been a good manager for the linux kernel, but he is self-admittedly hyperbolic and statements like these show that he really doesn't have an issue running his mouth about things that he really doesn't understand.
It is the old problem with software engineers: they think expertise in one field or one area makes them a certified supergenius with relevant input in completely unrelated areas. I can't count how many times I've seen someone on HN suggest One Weird Trick To Solve Hard Problems in [aerospace/materials sciences/etc]. Linus suffers from the same thing.
His experiences with NVIDIA are probably relevant, and if so we can discuss that, but the fact that he gave someone the middle finger in a Q+A session is not. That's just Linus being an asshole.
(and him being a long-term successful project manager doesn't make him not an asshole either. Jensen's an asshole and he's one of the most successful tech CEOs of all time. Linus doesn't mince words and we should do the same - he's an asshole on a professional level, the "I'm just being blunt!" schtick is just a nice dressing for what would in any other setting be described as a textbook toxic work environment, and his defenses are textbook "haha it's just locker room talk/we're all friends here" excuses that people causing toxic work environment are wont to make. He knows it, he said he'd tone it down, that lasted about a month and he's back to hyperbolic rants about things he doesn't really understand... like ZFS and AVX. But hey I guess they're not directed at people this time.)
Again, if he's got relevant technical input we can discuss that but "linus gives the middle finger!!!!" is not the last word on the topic.
