All those GWh wasted on “mining” only got us closer to the edge.
Which is why a lot of cryptocurrencies adopted proof of stake in favor of proof of work.
Not like the millions or billions of man hours wasted to make 50-ish removed into defacto-gods.
The GPU mining got me a free GPU and several hundred dollars, for the cost of about 10 cents per KWh. I’d take that “scam” any day of the week, and so I mined until it was over for GPU mining. No regerts.
And that money came from someone. You can’t win in crypto unless someone else loses. Typically it’s vulnerable people wishing for a get rich quick hack who lose.
You probably don’t really know how much of it works. I was paid by a mining pool, for completing blockchain work segments. The mining pool being a for-profit enterprise that pays GPU workers to mine coins that they keep or sell for profit. If you want to extrapolate that to the extent that you imagine I’m harvesting someone else’s wealth, then you’re going to have to warm up for an intense workout of mental gymnastics.
