> Instant messaging and calling is extremely valuable.

They, and I, are disagreeing with you. Instant messaging and calling are nice-to-have at best, and a huge burden at worst. They teach an extreme codependency that has little benefit, and causes a lot of anxiety.

They're convenient when somebody needs to go to the hospital, needs to get picked up, you can't find somebody in a museum, you're at the store and somebody at home might need something.

You are rarely using it for this. You're mostly wittering on and on about nonsense and not giving each other any room. When others go silent or don't answer quickly enough you get nervous about what they think about you, or if they are in danger. When others are interrogating you about things that make you uncomfortable, you feel like you have to answer now or you're making a statement with your silence.

Most of the useful stuff could be moved to a house phone (which doesn't exist anymore) and a payphone (which doesn't exist anymore.) For the people farther away, writing a letter was better. You don't need to be on the back of somebody 1000 miles away. There are too many of them, and companies and governments slip in. It's not healthy and it's not safe.
