on Apple's new technology
So Apple has apparently developed 'transparent texting' technology which would overlay messages on to a live video feed from a rear camera, allowing people to text while they walk.

This sort of thing makes me despair – spending money to develop technology that would not be needed if people were not so stupid.

How about simply watching where are you going while you are walking among the other people instead of texting or reading? Several times a week I see people walk into the road without looking because they "are texting". Another problem is when they are listening to music. Even if they are looking up, many people forget to check the road before stepping into it.

To be even safer, why not to build a feature into phones that shuts the screen off when it detects the user is walking? It would not be too hard as technology that detects footsteps has existed for years infitness gadgets.
