That is precisely the root of the problem. That means that the interpersonal relationships with friends and family have been hijacked by for-profit organizations pushing "more interesting" content. This contributes to dividing society even more.
Similarly parents not being attentive enough to their children is also sadly not new. (Satisfaction is also likely elusive for kids given the sheer craving they have proving incompatible with maintaining a house and necessary income.)
Although I wonder about the psychological impact of that being combined with helicopter parents going full surveillance state as the discourse shifts from "Tracking bands on your kid? That sounds stupid and horrifying." to being seriously considered and accepted. Like asking for a very locked down "can call only them with GPS" wrisrtwatch-phone." Society pendulums too much for linear social progressions and I hope it does so before we reach "You don't have trackers on your kid what the hell is wrong with you!" norms.
It must be frustrating being constantly watched yet never being able to receive attention when desired.
It is very rare that you really have to talk to someone, IME. Usually, it's more of a..."I don't really like or have a lot of common with this person but I've known them forever so what the heck"
No you didn't. You read a newspaper or magazine. Even growing up in the 80s I remember sitting around the table, each of us reading a different section of the LA times, and then swapping 1/2 way through the meal.
Also, before smartphones, people were smoking to have something in their hands.
Technology, especially the widespread technologies like smartphones are something that just happened upon most people.
So most people haven't adapted on how to use them responsibly. Just look around the average cafe, you can usually find a group of people sitting together but not talking about anything, they just look at their phones.
This also seems to reveal an underlying issue, one which I also experienced. Before smartphones usually, you'd make up conversation, smalltalk, even if you didn't want to talk or had anything interesting to say. These days instead of doing that people just seem to ignore each other and do something that is interesting, using their phones.
