But it is right now.

We don't live in a world with carbon neutral power generation. We're not there. PoW is even encouraging people to bring fossil-fuel based generation back online just for mining and making the transition to low-carbon economies slower.

Yeah, let's have that argument when we're closer to actually having that. Oh, and before you say "Increased demand will get us there sooner"... no, it won't, we already have a huge amount of demand that can't be met, it's making things worse.
