Moore’s law and materials science. On the Moore’s law side, pretty good levels of 3D rendering have become commoditized and are already miles ahead of what we could do not so many years ago for millions of dollars. Cheap, fast computing power is thus the muscle that’s driving this today. Materials science, on the other hand, is bringing us better chips, improved optics, sensors, actuators and displays. These things are driving our experiences in the virtual world and opening up great new possibilities.
