I figured someone would roll in with a weak gotcha that misses my point.
Also notice how I said with few exceptions, so it's even less impressive. You really got me good.

Function stacking is an important principle of permaculture. People using miners to heat spaces. Compost toilets. Fencing that keeps in livestock and are windbreaks. There's a million examples of shot that do two things that are way more beneficial than single use crap
And I also said maybe two things right in the note. Did you even read the whole thing?
My point was more about reducing complexity, not literally only having exactly one and only one function for every item in existence. Hell, you can even have three IF it makes sense for a particular application. But adding a glucometer and an air freshener and whatever else you can pack into a mining heater is probably going to make it more complicated and overall less reliable.
Buy a coffee maker that does 20 things if you want. I don't care. But it will probably end up in a fucking landfill and do nothing particularly well while it isn't.
