(small nit: yes, Chia does use HDDs, but plotting is mostly done on SSDs, afaik? and yes, not that important) I believe mining today in the US is 70-75% sustainable, which is pretty good, if true. (I haven't done a deep dive on this to confirm, seems a bit high). Personally, I find the notions of reducing energy usage in general quite terrifying. As we go up the Kardashev scale, our energy needs will keep rising exponentially, and for human civilization to pass the Great Filter we have no other choice but move and move quickly, but of course not too quickly to commit suicide. Not sure what's the best way to achieve it, but it is very hard to believe we can become a multiplanetary spacefaring civilization on a combination of hydro dams, windmills and solar panels. My hope is that Bitcoin can stimulate development of clean nuclear, or if we get lucky, maybe even aneutronic fusion.
