“Billionaire” is largely a responsibility the market gives you: you have to command billions in capital. It’s actually a job a the end of the day.
We should have high standards for who is allowed to have this job. Huang should be replaced as easily and quickly as any mid-level executive who costs his company 340 billion in market cap.
Replaced by whom though? Think about him what you will, but he is not your typical ivy league MBA CEO. He built Nvidia from the ground up, while being very technical and involved, and has done a great job at that.
He is not that easy to replace.
