I think its wishful thinking. It will be always more efficient (cheaper) to design a device that has loud fans, big power supplies...etc Also you can't heat your house all the time. Even if it catches on, the home miners will quickly become unprofitable while the industrial miners upgrade their equipement...

Idk there are lots of low hash miners out there humming away. If you can heat a space and earn some sats in return it’s still a better option than just turning the heater on.
Four blocks have been found by bitaxes the past few weeks. It’s not impossible. So lottery mining heaters have appeal too.
I didn't mean it wont happen to some degree, but not enough to break up the centralization in a meaningful and persitent way. I see more hope in electrical grid balancing, heating/preheating in industries (factorys...etc). So more spread out, so its not just concentrated in mining farms...
