I can think of the coolest UI's and 'experiences' but when you go to plan those out and map out the structure you soon realize stuff is harder than it appears on the outside. Kind of like a commercial I've seen recently that shows a couple walking into their house and everything they touch or use expands showing all the intricacies of modern conveniences. Things are so easy to do nowadays without knowing really 'how' they work.
I think this is an interesting point in our history. We can pick up anything nowadays without having a clue as to how it works. We lose sight of what it takes to bring something from idea to reality. More people need to become aware of how things work. This kind of makes me rant about how a lot of people I see constantly refuse to learn how things work. I see friends that have cars and they break and they just take it to a mechanic and let the mechanic worry about knowing how it works. In a sense that's nice but in another sense it's scary. I still may take my car to a mechanic but I at least know how it works to a certain depth and what could cause the problem. The same scenario for computers to proper zombie invasions. I'm guilty as much as the rest but I still try to keep a handle on things.
