That's what I'm working on right now. It's just that I can use all this expertise around me to do it. Everything repeats in technology and what you learned can and will be applied to new trends like Ethereum.

I don't recommend anyone to really go to Google to work on the future (besides perhaps if you want to get an edge in AI). It's just that SV has a lot of people that have accumulated experience while building Google, FB, etc and that helps a lot no matter what comes next. You get a lot of experience and people able and willing to take risks which is a nice basis to build something new.
