I agree. Even the platonic ideal of something like Facebook isn't really a problem (assume a Facebook with a chronological feed which shows nothing but what your friends and liked pages have posted, and it'll be a lot less addicting than what we have today, and a lot more social!). It's possible to have a phone and not have any apps on it which are engineered to make you addicted. If the relevant companies behaved themselves, we wouldn't be in this rut (or at least not as deep into it).
