the vast majority of us private individuals don't really *need* the Internet as such. it's mostly about convenience and amusement.
cellphones? it has saved lives and helped parents find their kids, so it's arguable that it has added value for the ordinary person.
but the Internet? there are a *few* cases where it's added value, such as video calls with far-away family members. i don't think social media has really added any value at all. online news?
i mean, frankly, it was less distracting when the news was something you consumed once in the morning (the newspaper) and once in the evening (the evening news), and then just went about with your life.
TV added some value, but also got us addicted to screens for the first time. it was a premonition of things to come.
