I think people tend to over romanticize the past.
You need to also take into account all the new interactions technology allows, like being able to videocall people from another continent for example.
Perhaps the way we interact with each other is changing, but interactions as a whole are increasing. Steemit is an example.
And I believe technological innovations are necessary for our survival. If our technology doesn’t evolve, we will cease to exist.
I'll agree with you on the video call eventually that it can count as human interaction. But social networks are for me just an illusion of real human interaction. I still like them but what I'm saying is that many people rather communicate via their phone instead of a direct conversation...
I think technology and human interaction comes in waves.
When AIM (aol instant messenger) first came out, I was a young teenager. My parents wouldn't let me go out late at night without supervision so I didn't have a good way to talk to friends at night except for texting. AIM completely changed that. I would spend hours talking with my school friends about everything. It's pretty much the only reason I learned how to type quickly. Without that technology, I wouldn't have talked to my friends nearly as much.
Now with FB, Insta, Snap, & ..., the connections feel shallow and fake. I tend to avoid most of the modern day social media. New technologies like VR chat seem very promising and will probably enable new forms of communication that people appreciate until corporations finish monetizing them.
