Modern shading languages and the prevalence of modern GPUs.
The GPU is also a low cost parallel supercomputer with tools like CUDA and OpenCL for blazing fast high level parallel code. Thank you to all those gamers out there driving down the prices of these increasingly impressive hardware marvels. In the next five years I hope every new computer sold (and iPhones too) will have the ability to run massively parallel code as a basic assumption, much like 24 bit color or 32 bit protected mode.
