> Any AI. they ...

I think you're incredibly disconnected from how most people use computers, and how most people hate computers, because they're a means to an end that often just get in the way.

My mom isn't going to use AI, or go to a library and read books, or read documentation about who knows what, to fix her computer. She's going to do as most people do: if something goes wrong, you take it to a place to fix it. And, that's good. Computers should be boring things that help you get actual things done, with the OS being something that lets you open apps, just as all the subsystems in your car are just something that lets you push the gas and get somewhere.

> that it takes less work to maintain

What is "maintain"? This concept does not exist for the average user. What they see is that their system sometimes reboots, or takes a bit longer to turn on, for some sort of update. Who knows, it just does that sometimes. There's literally nothing beyond turning it on and off, and opening apps.
