Why virtual reality is necessary on a planet of 11 billion

Virtual reality is more than a trick. It's a solution to big problems.

  • According to projections shared by the UN, Earth's population is expected to reach 9.7 billion in 2050. By the year 2100, that number could increase to 11 billion. Virtual reality will be necessary to reduce the waste of such a large population in industries like transport, retail, and manufacturing.
  • As an existing technology, there is a lot that virtual reality can do: rich and immersive environments, heightened storytelling, emotionally resonant experiences, and increased productivity in retail. But it's only in its infancy.
  • As the world's population continues to grow, the technology will need to evolve to facilitate a larger network of users, and developers will have to think harder about the technological potential and the ethical, neurological, and emotional side effects.
