Don't we give up a certain amount of freedom with self driving cars, though? Giving up control to a computer. Capable of being tracked everywhere. The possibility of total override of human control....etc.
Also, bitcoin is obsolete. Cardano, Dash, Monero, and some form of ethereum will dominate the marketplace soon.
Still though. Love your work. I still remember meeting you at the Free Man in Dallas. It was a turning point for me. It turned me into an indefatigable optimist.
