On: Ask HN: Why does cryptocurrency subjects on HN lack curious conversations?

[Scarblac]

Energy is fungible, we don't have 100% green energy and won't for a very long time, we make up the difference with fossil. Even if crypto used green energy only, it means more fossil burned.

To continue human civilization we need to stop fossil burning as much as possible, crypto is unnecessary and should therefore be stopped.

But that is solved with a price on carbon. That would make mining without renewables unprofitable.

How do you argue that something is unnecessary? Aluminum uses heaps of energy… we haven’t needed in for 1000s of years, is it neccersary?
