How many people left Nvidia over the years to get paid a bit more money? Perhaps it worked out well for them.
But what Huang did shows how long term vision of a start up can really pay off. He is one of the richest people in the world as a result. Of course, many of his employees already are in a fine position.
Ironic that I bet most of them, in spite of being worth tens of millions, still show up for work each day.
