> Are these "planet is heating" people going around telling people not to have idle appliances plugged in? Not to use bigger cars if not necessary? If BMW was using websockets in one of their huge SUVs would you not help them?
Any PoW system that is currently running right now to process, mine and settle a transaction on-chain is indeed 'burning the planet' which I agree. The thing is, not all systems are like PoW and it doesn't apply to all cryptocurrencies and Proof of Stake (PoS), hashgraphs, and mostly byzantine fault tolerant consensus algorithms are not burning up the planet. There are alternatives that are useable today.
Unlike the deep learning systems continuously training their surveillance data every day that have just burned up a data centre yesterday. The tech bros don't want to hear that but will target crypto because it threatens their day to day business, especially with the author as highlighted by some commenters and even some ferocious anti-crypto supporters like the CTO of Adjoint, a private blockchain startup.

They also lack any reasoning other than 'all crypto should die in a fire' which isn't going to happen. So at best, this is indeed a very childish and an extreme position to take.
