Yeah, it's very typical human to double down when things start to go wrong. It's this kind of stubborn bloody minded mindset and a lot of luck that saved Tesla when it was balancing on a knife's edge and same with SpaceX, he kept pushing his crazy ideas but they worked out in the last second. However, Twitter is a different beast entirely, it's not going to be saved by manufacturing, it's about something Elon Musk does poorly with: people.
