The grid both is and isn't unreliable. I've not had many random outages, but I have had 2 x day long outages on hot Friday's when they were replacing power poles, which the generator of course kept me through. Working from home, and being in the Texas heat, that would be bad. And I like many people now have really bad power outage PTSD after the 2021 Texas Freeze where we all lost power. I'll never let that happen again! And turning everything off is such a hassle, I want it to to all stay on no matter what. Since I work from home, that adds another layer too. Plus, I just like cool things

Yeah that seems kinda crazy to me too. I've lived in my current house for 8 years and the only time the power has gone out was when a vehicle crashed into one of the distribution boxes by the road. Our power and internet come from the same provider so it was a double whammy for several hours.

But I suppose it depends where you are - i worked at a place that had two independent power feeds from two different cities, massive UPSs to run the datacenter for 10 minutes and then two redundant diesel generators with several months of fuel on site. I still saw that go down twice in my time there.
