I was just going to comment on this book; one of my favorites as well. The follow on book "Thinking Forth" was similarly mind opening. http://thinking-forth.sourceforge.net/
I would like to make quick (<30 min) transactions of large amounts. I can do that with BTC, but it would be nice to do this with USD. Currently, this involves finding a bank, go during the right time, proper account numbers, etc.

You actually mean spread an opinion. I doubt any one citizen would conduct a trial or research; some may actually look at data, but that is rare. These are opinions, most likely biased by a belief.
Most MDs are general physicians and know little about vaccines other than textbook knowledge that is decades old. Why would you trust them over a team of researchers? Especially at this point of the pandemic when we have so much data showing their effectiveness?
They are limiting mining of a single coin: Ethereum. Nothing is going to stop mining other coins, which are quite profitable. Also, Ethereum is going through two upcoming events which will change the landscape dramatically. July has EIP-1559 which will reduce ETH mining earnings by 30% and the eventual move to proof of stake in late 2021/early 2022. Both of these events will make other non-ETH coins more profitable.
Staking (for Ethereum 2.0) will be the mechanism over the current proof of work method. This will reduce the energy cost significantly by removing the requirement of mining.
