I think right now emotions are flying high, so people are going to make grand statements (and of course the press, which now hates Musk, is very gung-ho to publish anything.) I'm sure some systems will fail, but as to if the general public will really notice much of it, I have doubts. I could be wrong, but I've seen employees make similar claims after being fired or leaving and generally most everything working out. Interviewing or getting information from people fired up after an event like that are generally not reliable, in my experience.
