Large swathes of Europe have winters as bad or even worse than New York's. I've grown up in one of those countries and had never seen a home clothes dryer before visiting the US. I've also almost never seen them in London or Berlin where I lived after that and those have at most marginally warmer winters than New York.
I dry my clothes on a line in the winter in New York. It's below zero outside, but like 80 degrees and 0% humidity inside my apartment. Clothes dry fast. (And the space was already being heated, because I live in it, and it's against the law for the landlord to allow the temperature to go below 55 degrees, and they are paranoid, so it's more like 80-90 all winter.)
The heat is on a timer so it's not like this all the time, but I have to wonder what a world where thermostats have been invented would be like.
Electrical resistive heating clothes dryers are an enormous energy hog.
Heat pump water heaters, though, are supposedly much better than resistive.
Classic whataboutism. First of all your entire comparison makes no sense, you have to compare alternatives for use. What's the alternative to a dryer. Using a line and hanging your clothes. Fair enough, what about in the winter in New York? A ventless dryer? Doesn't use substantially less energy. And so forth.
For every conceivable use case there exists alternatives that use orders of magnitude less energy. NFTs, sending money, federated computing, you name it, something already exists.
The only reason blockchain is a thing is because cryptocurrencies are booming in terms of how much they're sold for. The end.
