Re: "compared crypto's electricity usage to that of video games"
Oh, it's time to go over this again?
Coin is stock? In a company with no sales, assets, or employees, and a board that anyone can join; where the board members compete to issue themselves stock according to rules which can be changed at any time by a majority of the currently issue rate of the stock? Just TRY to get that approved.
I'm just getting started.
When I read the details of the Etherium VM, I (being a mathematician with a decade in software microprocessor validation and an expert in integer programming) yelled at the air for half an hour. The VM more-or-less led programmers into the bug that triggered the Etherium Fork. And anyone with a background in security, validation, or integer programming would have known this. These instruments are being created by people with callous disregard for the basics.
Moreover, the explicit goal of these instruments is to undermine the sovereignty of the nation states. While I very much want fiat to be replaced with something like a gold standard, I'm not stupid enough to think that if coin ever actually threatened fiat that the entire force of government would come down on it.
But the CAP theorem puts a hard limit on what a (purely theoretical) perfect coin can do. The incumbent system has spent centuries fiddling around to fix C. Coin must be strongly CP, which means that A is in the air. And no one is going to wait an hour to settle average purchases.
