Despite the fact that it's failed to catch on every single time, virtual reality is still a staple of science fiction. In the future, it'll be virtual sports and virtual walks through virtual forests. Virtual movies and virtual sex. Almost nothing we experience anymore, in the year 2099, will actually be real - just a carefully curated and packaged simulation.
The scary thing is that in a way, this is already starting to happen. We're not talking about VR gaming headsets - those are just expensive motions sickness generators. We're talking about experiencing something through someone else's lens. Not looking directly at the Mona Lisa, but literally taking a picture of someone else taking a picture. If you can't see anything wrong with that, you're lost already.
