It was even called cyberspace.

I feel like cyberspace was never meant to use your real name and identity. The entire point was that you were free from the constraints of the real world to be something else.

Cyberspace is still alive and well though at the individual level. The only social media I have is twitter with no followers and I have never posted anything. I don't cultivate any kind of online "brand" of my real world self. My twitter is basically an art machine that shows me wonderful works of art. Even the slightest mention of political nonsense, I block the sender no matter who it is.

Society is a lost cause in this regard but the individual can still enter cyberspace if they want to.

The real lost cause is even the word "simulation" is lost to a science fiction computer internet fantasy as opposed to the process of creating and sustaining simulacra like most people are spending their lives doing on social media.
