Wrote this in 2017, still makes sense.   There is an industry to come around tele-operated robots, and it could be a uniquely American industry with jobs for everyone.

Civil online places will not be possible until there is a safe system for establishing singular, non-PII based identity.

To correct the escalating wealth inequality inevitable in free markets, make a currency that uses a sales tax to fund a basic income.  Can be done with a cryptocurrency.

Distributing simulation of a virtual world across tiled servers so you could make a really big space.  Still hasn't been replicated broadly in gaming.


Back in the days of modems, at RealNetworks, we were trying different ideas to better measure how bad your connection was.
