The problem isn't smartphones. It's apps that appeal to addictive persona, be they social media or time consuming games. Use your smartphone as a tool and it serves a purpose without intruding on your life.
I'd buy that if all the research into making them addictive wasn't pursued. Just like cigarettes, a lot of people are being targeted by the addictive nature of these devices. Sure, there's some people who just won't smoke, no matter what. But if you look at statistically significant portions of the population, how they were directly targeted by marketing, and then saturated with a physically addictive chemical (constant dopamine rushes that impact the brain in the case of smart phones and apps), well....I'm pretty sure the argument holds up for a large part of the population. Saying "just don't do that' just doens't work.
