OK, I’m old. I don’t have a smartphone and I want one even less after reading your article. When you don’t have one, observing the behavior of those who do have them (nearly everyone?) is alarming. People seem to be permanently distracted. Any country that wants to ruin the US doesn’t need nuclear weapons or suicide bomber. All they have to do is take out the grid that runs phones and computers. Most of the country would then be toast.
