Mind you the Great Oxidation Event wiped good chunk of life back then.
Mainly because oxygen was toxic to anaerobic life and it also oxidized methane making Earth into a snowball.
We did not exist back then. And cyanobacteria did not have a great plan of creating mammals.
The random waste from cryptocurrencies just turns into heat, so I expect it opens up ~zero new possibilities. Have fun though!
How is cryptocurrency waste heat different from bank server waste heat? Only because crypto has a dramatically worse efficiency? I guess both my crypto wallet and my bank account are products of waste heat that produce zero new possibilities.
And then I'm separately making the claim that using proof of work won't set the stage for anything interesting in the future, no matter how much heat it generates.
I'm not saying the technology is ridiculous, I'm just saying the overall implementation and outcomes would look like a madness to someone from the past or indeed the future.
Cryptocurrency is more ridiculous than both of the above, imo. Rai stones can be used as material, art can be looked at and enjoyed, cryptocurrency is random numbers controlling access to a ledger.
