And how do you think those disks get made? (And how do you run those disks without expending energy?)
- mgraczyk 5y agoThey do use energy, but it's very small compared to other economic activity. For example, suppose Bitcoin consumed as much energy as a few households. Would that be acceptable? Alternatives aren't quite that efficient, but my point is that the relative energy consumption matters a lot.
