Hey, maybe you are very good at address and data organizing. I'm serious. It's just so difficult for the majority of us. As relix said, if you find that easy, you'll make a lot of money working as a GPU programmer. That being said, there are many real world problems where there are so many data dependences that transforming the input into independent vectors is plain impossible. For those cases, letting the CPU optimize the datapath is better than programming a GPU version yourself.
