- ac29 5y agoBitcoin mining hasnt used GPUs in a long time. Its worse - it uses fully custom ASICs that still take up fab time and raw materials, but when they are no longer economical to run, they cant be reused for anything else.

If we figured out super cheap ways of making chips, the endless race would move to building factories or repurposing land for the whole system. It has to grow until it hits something hard to grow further. Security of the system depends on using so much resources all the time that an attacker can't waste resources any faster.
