Medium should have a whole separate category for concern-trolling articles written by privileged assholes lecturing the rest of us about how we need to "simplify".
If the unread email badge is causing you to lose sleep and you missed your child's first steps because you were trying to figure out whether to put it on Twitter or Instagram, it's not your phone that is the problem. You are the problem.
You deleted all but four apps from the home screen of your phone? Good for you. You have resolved to shut your phone off as soon you get home? Great plan. I hope that works out for you.
Personally, I like having the entire Internet on a rectangle in my pocket.
