True enough

Exactly! Intuitively this feels like a fiat problem. Organic hydrocarbon energy sources are one of the lowest time preference energy sources we have, it literally takes millions of years to be formed. And, only mining bitcoin as an economy isn't the the point of bitcoin since it's only a representation of the economy at large. So, burning such low time preference commodities for fiat profits and basically capital strip mining our global potential energy supply, I feel, can't work on a sound money standard. You need to use that energy supply for stuff you actually want. We don't wan't money/bitcoin for the sake of it, but because we can exchange it for stuff we actually want, i.e. better goods and services.

you do understand that building solar panels involves burning shit that's bad for the environment, and wind turbines/hydroelectric uses shitloads of concrete (which also involves burning shit to make) then the steel and aluminium and plastics and everything else involved.

something that requires more and more and more energy to be sustained over time is going to create more and more pollution, even if you get the energy from solar, you gotta make more and more solar panels to sustain the demand.

that said, computing power and energy efficiency will also continue to improve.

once they figure out how to keep those computers made from grafted human brain tissue alive for longer than 18 months mining Bitcoin will become a lot cheaper.
