I agree with you, but according to me smartphones are not the problem. The real problem is people who use them in the wrong way. In my opinion, technology is never bad, but it depends on how people use it.
The goal of the inventor of the phone was making work easier, I think, and not allowing people to film an accident. Nevertheless, there are people who film accidents. So, it's their fault, and not the inventor's.
However, you're completely in reason!
