You being up an interesting point. Let's expand electricity a little bit.

If I flip a switch the lights come on. I don't need to understand it but someone does. And because electricity can be deadly of handled wrong, everyone in your proximity handles electricity the exact same way (and this is enforced via law). This means only a few people anywhere need to have the deep knowledge of how it works for the rest of us to get light.

Compare this to computing - sure you click the button and get Facebook but that button could be designed any number of ways. Like electricity the generation who tinkered is past (well passing), but unlike electricity firm standards on how to design your Facebook button have not been written in blood.

I for one am terrified of what the next 10 years of the business IT landscape is going to look like as we need to start absorbing kids who grew up on iPads.
