I agree, while it is fine that the computer does the thing being an IT person I am *always* worried at leaving my fate to somebody else's programming skills :-) How many times haven't we used a computer program where you are totally hindered by what THE PROGRAM THINKS you want to do and doesn't let you DO THE THINGS YOU ACTUALLY want to do?
For that same reason I don't think I would like to have a car with Windows embedded into it (unless I don't know about it).
Pilot skills are also lost, while they can practice it in a simulator it is not the same state of mind as in real life where you have the lives on hundreds of people at your hands.
I mean, even right now with GPS who does high altitude VOR tracking??? skills get rusty and then something bad happens and eh... uh.... what was that that I needed to do?
