I think we're coming from different angles, but are likely to end up in the middle. You don't need to know everything yourself. But you can derive a lot of power over your environment just knowing what things are possible, and who to ask for help (and how to ask it!). To do that, you need to know a little bit about a lot of fields : mechanics, engineering, electricity ... and definitely including programming, because that's everywhere these days. That's one argument at least. [[ Another argument is that it really does help if you're not helpless to hold a screwdriver, put in a light-bulb, change a tire, or write a small program. But that's for another day. ]]
