Because the higher assurance of reproducibility and stability is a starting point that enables other things.

"50% power reliability is enough for anyone, I sometimes don't have to gather firewood"

Its hard to imagine never gathering firewood to heat your home in that reality.

All of this to say that you can make more assumptions and enable things that were not possible before with better reproducibility.

I get your point, but I'm more on the side of "let those enthusiasts get shocked and see in a few years if this electricity thing is really worth it".

I eschew complexity wherever practical. There's so much complexity in modern life, especially for tech people.

Right now mutable Linux is absolutely fine for me, but I'd like to thank all the people that are alpha testing some of the tech I'll adopt later ;)
