No, obviously not. Smartphones are a mixed blessing, I'm not sure we're better off with the little distraction machines, but both them and electric cars were things that could plausibly have developed more slowly, deliberately and thoughtfully over time without being "juiced" by distorted market incentives. They could have developed by companies simply evolving phones and cars over time.
They are quite useful as GPS/camera/general info lookup devices.
But virtue of having web browsers they also channel social media. Having social media come in through our phones does make it worse, but it was already bad even on laptops. (Writing this on a social media site using my phone is kind of funny).
