I'll admit to some nerd shit and say that the Mars trilogy was an important part of my becoming a leftist. It got me to question my capitalist realism and think that maybe a better society is possible. I'm reading his most recent book though and he has this long, weird riddle thing where the answer was blockchain and I found it super off putting.

Yeah, that shit is indeed a disaster. It’s not inherent to crypto currency though, only to certain implementations.
Something like burst coin uses like 1/500th the energy as Bitcoin does.
Proof of Stake is a good alternative that ethereum is pursuing, hopefully that works out.
