It sounds like you chose to stop learning about cars after manufacturers stopped using carburetors.
The point still stands though - some people like to hear that the computer they're buying "just works," and other people like to know a little more about what goes on under the hood, so that they have a better idea of whether or not they're getting shafted by their, uh, mechanic.
Read what I said again. You'll find that actually all you can infer is that I have a car with carbs; there's no information there on how much I know about anything else.
So if (hypothetical, not real world) Apple were tomorrow to remotely turn OSX into an iOS like system where everything is centralized and the internals are locked away, I'd be really disappointed. Because I'd ultimately have to choose to use a "super-user" system, but that means switching to some other one that I don't care for as much.
The message of this post and others seems to be "We like that you're making everything simpler, but please don't take the power away from those of us who need it. We don't want to switch, so for everyone's sake, please don't make us".
Pringles? Cheetos?
