I used to think Elon Musk was a smart entrepreneur or whatever, until two things happened: I bought a Tesla, which started to sow my first doubts about how well his execution is going, and then he bought Twitter and started taking direct control over software engineering activities inside it.

I happen to know a lot about software engineering. As a result, I now know he is completely incompetent. 🙃

@ariadne Back when I used to hire people I discovered that one of the most important skills to hire for was “good judgement.” And one of the key requirements for good judgement was self-criticism. Self-criticism is how you improve your judgement, because you’re the only thing you actually control, the only thing you can actually change. I also discovered that good judgement was independent of intelligence. Musk doesn’t seem to do self-criticism very well. Smart, but same mistakes, over and over.
