And on that I agree with you. But we are moving away from that now that Crypto (especially Bitcoin) is becoming mainstream and actually quite relevant in society as a whole.

I do believe that the way forward is to commoditize Bitcoin mining into appliances and other forms of electrical "subsidies" for consumers. Honestly, that is really the most plausible route to decentralized mining that I can  if that is what we're aiming at. But I digress, right now we are in the sweet spot of Bitcoin mining (regardless of what people say about profitability etc). The mining curve vs. Adoption rate (growth) is at its peak right now. After this, price growth will flatten out, and mining profitability will shrink after the next halvening enough so that by the time 7nm chips become mainstream, it probably won't be fun to have a dedicated mining facility anymore.
