There is for sure a lot to be said about this stuff. I think phones are both an indispensable device for modern access to the worlds information, as well as one of the most insidious inventions foisted upon us.
Phones have most definitely done a LOT of good in the world. Being able to call someone for help in an emergency if you've fallen on a trail in the woods. Not everyone would bring CB radios in the past, and sadly a lot of people died from exposure or something else. In that regard, I think phones have saved a lot of people.
It has also assisted a lot of people in their suicidal attempts and ideations.
Where I think I'm going with it is to say that it is Yin and Yang. We cannot have the good without the bad and we cannot have the bad without the good. They are forces that balance each other out in the end!
