Exactly. People here think knowing how to code is spinning up 5 k8s clusters and running an ELK stack from scratch, when in reality, it can be much less. Musk was an intermediate level coder from his time, which, mind you, was a time where terms like Agile, code hygiene, etc, were non-existent.
Most code critics of Musk today criticize his poor coding skills due to him unable to migrate his skills from that era to today. But as CEO, he doesn't need to do that. I'm sure he understands the code on a shallow level, which is fine for his role.
