The best comment on this I've read on Mastodon went like this (Rod Hilton @rodhilton@mastodon.social)

He talked about electric cars. I don’t know anything about cars, so when people said he was a genius I figured he must be a genius.

Then he talked about rockets. I don’t know anything about rockets, so when people said he was a genius I figured he must be a genius.

Now he talks about software. I happen to know a lot about software & Elon Musk is saying the stupidest shit I’ve ever heard anyone say, so when people say he’s a genius I figure I should stay the hell away from his cars and rockets.

This rang a bell for me as I, too, know a fair bit about software, and indeed, he has been saying moronic stuff about it. If I interviewed for a job and the interviewer spouted any of that I would have thanked them for their time and left.

[note: apologies to anyone who applauded this before I found the actual quote and author. I’d paraphrased with an apology about not being able to find the post. I’ve fixed it now, feel free to un-applaud it if I’ve changed meanings — wasn’t my intent]
