In an ideal world, you shouldn't have to worry about it.

In this world, you do.

For us, it's a means, not an end. If we don't find it fun to write shell scripts, compile source code, and other hacking tasks on our own computer, does this mean we want software companies to own our computers and decide what we do with the spokes of our digital hub?

Regardless of the OS, you should know how to work your computer to the best of your abilities. If you cannot do it yourself, you are automatically putting yourself in the hands of others. This applies to cars, home repair and computers.

The middle ground is struck between personal knowledge and the knowledge and leverage thereof of others.

If you have a servant, don't you want that servant to be autonomous to a certain degree?

A computer is a tool, not a servant.
