You seem to judge the world by your own accument and ability, which is very dangerous.

Many milions of people are scared by things such as red and black wires and wont touch them with a barge pole.

It's ridiculous to baby proof the world to that level. For a significant portion of that group, taking a screwdriver to their phone is also beyond comfort — those people can take their phone to a mall kiosk just like they do now.
