Now, instead of using primitive 300 x 200 pixel LCD displays that were prohibitively expensive in the 90s, we are looking at a world where display will be in beautiful 4k quality. Meanwhile, accelerometers and gyroscopes can measure head movement, and modern computing power can reduce lag and latency. It took many years, but finally the true potential of VR is being realized.
Like virtual reality, there are 10 other emerging technologies that are finally ready for prime time. Some, like the recent advances in artificial intelli
