They are not required for society to go on, and would not significantly change the world if they were to suddenly disappear. Try saying the same for cars, planes, electricity, the internet, etc.
They do have uses, and have been a result of innovation. But the same could be said of Sporks, Jeans made out of Sweatpants, and non-stick ketchup bottles... it doesn't make any of those other things required by society any more or less than smart phones though.
