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 think this concern has been paid attention to due to Elon Musk's reasoning on why he stopped using bitcoin as a mode of payment for Tesla. If we would put environmental concerns to our ways here in crypto, I find it reasonable why many people are concerned. Considering the fact that every resource from our natural environment has a limit, regardless of the time span it may take before it gets consumed completely, we should still find a way on how we can make it last longer. In the case of crypto, maybe there is a way on how we can consume energy and at the same time replace the energy used so everyone would agree and everyone would still benefit.
