Imagine a world where energy output scales 1000x or 10000x today on ultradense and/or clean/renewable standards.
A small fraction of that might involved in allowing humans to live in abundance and or terraforming the earth in the name to environmental reclamation.
The rest of that energy could all be directed at bitcoin mining and the difficulty adjustment would just do its thing.
But hopefully be then we’ll be interplanetary (minimally) and thinking about thinks like Dyson spheres and finding and killing The Engineers…
