It is unquestionably terrible for society as it currently exists.
People who do not understand the technology NEED to watch the documentary, "The Social Dilemma."
It is on Netflix.
Agreed. Like Lanier says, it's all about changing behavior. The O.G. internet was a bunch of hippies + DARPA. I was on "The Well" back in the early 90's. I was on Prodigy, Compuserve, and the other one before that. Before that, I was on dial up BBS's.
People had sense of community. It was idealistic and continued that way for a long time.
Once people figured out that you could monetize behavior, and once big capital got involved - it got scary, like it is now.
Here's where it gets even wierder. Since the dawn of humans we have worked on what I call "shared reality." That means that people in a given area generally see things about the same way. Example would be Britain before there was Great Britain and Brittany. The Celts saw reality in a certain way as part of their culture. The Romans came and saw a different reality. Those realities eventually merged. Same with the Mongols and Han Chinese. Same with every conflict between cultures. Over time, a shared reality emerges that incorporates aspects from the constituent cultures.
Now we don't have that. I can be sitting next to someone on the bus, and their entire view of reality is so heavily mediated that they see the world through an entirely different lens. It's like that everywhere now. It's not just the old "tribe" thing. Everyone is now their own "tribe."
