Another year, another step closer to real-time ray tracing. This is as good as it gets in 2014. A little noisy but I'd say give it a few more years, a few more teraflops of GPU power and we will be seeing games, phones, tablets, you name it, rendering reality. Reality like what you see out your bedroom window, in real time.
Then what will happen to the world? What happens to film making when you don't need to walk out the door to film something? What happens when you can really start to think about building The Matrix?
Facebook + Second Life + GPU + Brigade 3.0 = The Matrix?
Only time will tell. Perhaps the next World of Warcraft will be more immersive than we dare imagine.
