(Or did you just factiously mean that people have smart phones on them which can function as torches?)
Here, if you go the the pub at night as the streetlights are turned off at midnight, so you take a torch (your phone as a backup). Its perfectly commonplace. To suggest this is "anti-pedestrian" is a bit silly. Rather, it's anti-light pollution.
Yes, generally the purpose of the light is so others can see you.
My god, we spend all of our lives blasting lights into our eyes (some people call these lights "screens"), we've forgotten how to live without it!
I'm in an urban area, but it's not as well-lit as a downtown environment. There's street lights every 2-3 houses and they're not super bright.
I personally prefer this over a downtown-like bright environment since it makes it easier to sleep and the ambience is just better at night.
It’s easier than ever to carry one.
