I took a moment to participate in an ARIN (https://www.arin.net) call. They drive policy for IP addresses that run the Internet. Anyway, one thing that stood out to me was during a portion of the conference the organization was holding elections for open seats. The seats are open to anyone, I'm pretty sure.
There were a bunch of people, from across the country, MANY in retirement, trying their best to sell themselves that they are the right candidate.
Sergey can just make a phone call and he gets to build Gemini and run a billion dollar organization and have meaning in old-age. This is what wealth buys you. The rest of us, I guess, we will be arm-wresteling for the few open oppertunities to make an impact.
