Maybe software. I personally know multiple mechanical engineers (smart ones from Berkeley) who were worked into the ground at Apple. Like >55h work weeks.

Even if tsla is massively overvalued (which I agree is likely) that doesn’t mean it’s a failed business plan, a crash of stock price back to “normal” does not mean the business plan is a failure. Aka even without high valuations tsla could have a toxic work place and still be stably producing successful cars.
