Just want to put this out there. What is the problem with crypto mining and energy consumption? Yes, I know you'll raise environment concerns, I get it.
However, consider this: a civilisation is measured by its energy consumption. Before we discovered fire and used any stone tools, the only energy we had was whatever our bodies produced. Then we discovered fire, made tools, invented the wheel, etc. Until now, when we use computers, robots and other machines to help us live. Our life expectancy and quality of life has increased dramatically.
Shouldn't we concentrate our efforts on using clean renewable energy, rather than restrict our use of it?
Frankly, if there is a problem with too much energy consumption, we should go back and live in caves, and hunt in groups.
I don't think we need to go back to live in caves to stop using energy for our own purposes. Why don't you consider the option that we are simply deceived and forced to buy something that is very profitable for someone? I am not saying that green energy is bad, on the contrary it is very good, but getting this energy at this stage of development is an expensive pleasure. Moreover, these technologies existed before, but they were simply not used as large players earned money on other sources of energy. Now, too, nothing has changed much, if it is profitable to make money on coal, then they will extract coal, who does not have coal, oil, gas and even wood, then of course they will try to use alternative sources of energy, while it simply may not be enough for industry and heavy production. Cryptocurrencies also consume energy, but not on the same scale as we can. All this, as I said above, is a game of big players, and everyone tries to defend their interests.
