Owning a car but having no mechanical skills, tools and somewhere to work on it can end up being costly. There are many car mechanics out there who can and will take advantage of your ignorance. Even an honest garage bill can be crippling.
I made a conscious decision early on in my computer use that I would get to know enough that I could fix at least basic stuff myself. I disassembled and the rebuilt machines and read books, asked people etc. until I was up to speed.
This was back in the mid 90s when PCs were just starting to become an indispensable part of 'normal' peoples lives.
Now they almost entirely central to everyone's lives (in the West). It makes
sense to me to have a at least a good basic set of IT skills, or you are going to tearing out your hair and opening your wallet of a regular basis.
The funny thing is now I fix global backbone optical networks. The PC is just a tool in that process like a hammer or a saw yet people still say "you fix PCs don't you?".
I still can't fix my own car. I'm smart enough but I don't like getting dirty, electrons and photons are nice and clean.
