> All of the things mentioned are already being done without VR headsets. Not all, no. You can't lay paint strokes in mid-air around you if you are not in a virtual reality with different physics. That art form simply did not exist before. You can't understand whether the dimensions and arrangement of a not-yet-built house or movie set is appropriate if you can't visit it in person. It's a threshold change from seeing a model or a 2d tour. If you are a burn victim, you can't "escape" your thoughts unless your visual cortex is completely flooded by imagery. Similarly, researchers trick the brain of people with spinal cord injuries to reconnect or regrow neurons. Again the "headphones-for-your-eyes" aspect that floods your input channels is used to trick the brain, and this was simply not imaginable before.
