Virtual worlds are not illusions or fictions, or at least theyneed not be. What happens in VR really happens. Theobjects we interact with in VR are real.
I don't completely agree with this thesis. Sure, when the goggles are put on you're tricking your brain into thinking what you are seeing is real. This is not necessarily true. What happens in the virtual world does not coincide with what happens in the world outside of the goggles. If we started to adopt this idea that the VR world is the real world then we would begin to neglect aspects of life and to an extent even ourselves and our health.
