I'm so torn on this, because on one hand smart phones have been a net positive in many aspect of my life. I get instantly access to maps, I have my bank in my pocket, I get notified of my bills, check my emails, communicate with friends and family, order stuff online..
Yet there is also the toxic stuff, constantly scrolling X, Facebook or Instagram, bombarded with ads, subscriptions and trash..
I think smart phones can be great devices but their use should be limited to useful functionalities rather than dopamine hits.
