Thanks for your detailed comment Michael.
I agree the energy consumption is a problem, though in an Andreas A. video I was listening to the other day, he said that the electricity usage for Bitcoin is likely close to its peak, staying about the same as it is now, despite increases in the size of the network. When people say it's a house worth of electricity for every transaction, that's rather misleading. Even so, it doesn't hurt to be more efficient, and that's one of the reasons people are interested in proof of stake, and Hashgraph too I suppose.
I hope you and your family are well.
