There seems to be a big gap between what people think others "ought" to understand. Like the expectation that changing tires is something someone needs to be able to do. Or one should be filing their own taxes. I can do both, but I'm never going to do either, because it's more practical to let someone with way more expertise and knowledge do it for me.

When it comes to taxes, for example, doing it would take a considerable time for me, to double check and verify everything, and it would be a frustrating experience. By hiring an accountant to do that for me, I save a lot of time and frustration, and can turn that time into work, which ends up netting me more money than my accountant's pay. So why exactly should I be doing my own taxes?

And changing tires: since we got our car some 8 years ago, we only ever had to change tires unexpectedly once. We called help, they were there in 10 minutes, meanwhile we nursed our one year olds back to sleep. A lot more convenient - and a lot faster! - than if we had to change tires ourselves.

To bring this back on topic: I believe that it is perfectly fine to be an end-user who can use their system, their programs, but delegate the administrative tasks to someone else. Installing, upgrading, and in general, maintaining an operating system is not a skill that everyone ought to know. It certainly helps if they do, but it should not be a required skill.

I actually feel one problem with the modern age, in america in particular, is this idea of everyone doing everyone for themselves. doctor, accountant, lawyer, mechanic, it guy, plumber, electrician. Initially gas stations pumped the gas, checked your fluids and tires, and would top you off as part of the service. no one did that stuff. if your tv broke you called in the tv repairman and you got your milk from a milkman. people were expected to know their jobs and not necessarily everyone elses.
