It's very complex to make something simple, by whittling away and reducing until you are left with the essence of the problem being solved. When it is achieved, the technology just "fades away" and you are no longer aware of the tool. It's just an extension of yourself.
As tools get better, they reduce the amount of stuff you need to learn to use them. Moving towards automatic transmissions in cars removed the need for a clutch, for the shifter, and most importantly, it eliminated need to understand that the car had various gears at all. The car is just magic.
You shouldn't need to learn about computers in order to use them.
