Since you can use it for just about anything,including writing to the framebuffer directly,I imagine in the future people will be making their custom rasterizers/(or some sort of voxel graphics) directly in the compute shader and also animations,vertex transformations and pretty much everything?I think in some paper a guy from Epic wrote something like that

The abstractions in pixel shading processing are very convenient. I don't think rasterization will go away any time soon. AAA projects might likely do whole renderers from scratch but who knows what will happen in the low end. The user does not really care, and compute is not so good on portables (when it's there, in the first place).

Personally I hope the current pipeline stays there, at least at logical level, for at least another 10 years.
