When someone says bullshit about mass manufacturing of cars, its hard to argue because we aren't mechanical engineers.
When someone says bullshit about running a website... guess what? Hacker News is full of programmers, venture capitalists, and website owners. Suddenly Elon Musk is speaking our language and what we see from Twitter is... uggghhhh....
Elon Musk hasn't changed much. All that's really happened is that he moved back into a proper technology discussion in a subject people around here are deeply familiar with. The standard levels of bullshit he spouts are insufficient when the audience here has a much deeper understanding of online advertisements, bots, user engagement, UI issues, and the like.
