Immersive high-resolution video streaming comes to mind. Gamers are going to love this.
Billions of non-functional people plugged into AI-generated virtual reality. They will be farmed in various ways. The vast majority will pick the option for total immersion, which is to say forget base reality and have their bodies maintained in artificial 'wombs'.
Those of us who must do things in the physical world to maintain the infrastructure for the virtual world, will live in hyper-reality with AI-generated overlays on the physical world we encounter. The level of information available in your overlay will be commensurate with your job title and security clearance.
The really interesting thing to contemplate is whether what I'm describing above is the likely future or the present reality.
