Effectively it is solely owned by Elon and other people have an equity stake. This is another huge risk. You have to trust Elon not to get distracted and decide to hard pivot to something else.

He is betting AI rapidly improves in a way that allows robots to become rapidly more useful and there is zero evidence that is feasible in the next 5 - 10 years.
