Silicon Valley has been a technology capital like New York is a financial capital.
There are a lot of billionaires in Silicon Valley, but in the end, we are all heading to the same place. If given the choice between making a lot of money or finding a way to make people live longer, what do you choose?
If you want to invest in early-stage technologies, putting a timeframe on it does behold you to Silicon Valley economics. You've got a certain time period where you have to make the money. And you have to invest that money whether you find good companies or not.
