Amusingly, I think Ted Chiang actually wrote a short story about this very concept (it involves people committing a form of suicide that removes their conscious experience but they still act and live in society as some kind of psychic zombie. I’m pretty sure it was him anyway, can’t recall the story name
Maybe “What's Expected of Us”?
I was trying to find it, but I read it a long time ago and I have a bad feeling I might have mashed a few different stories together in my head. That is a good story though!
