Umm... what? Why the namecalling?
There's CUDA and FireStream which are programming the shaders w/o going through DirectX/OpenGL.
As far as D3D11 -- I think the only support there which is similar is the compute shaders which I'm unsure if it will apply. There's also the Apple OpenCL initiative which aims to accomplish a similar thing. AFAIK, none of the GPGPU bare-to-the metal APIs allow you to render to a texture so I think it might not be possible to accomplish a pure Stream based rendering engine (yet).
In any case, I think his original point stands -- that the monolithic SGI based APIs are going to still be used (OpenGL/DirectX), but the hardware under the covers will be more exposed to allow programmers to be more creative with how they want to utilize the highly parallel processing that the new chips provide. Thus allowing programmers to do things in software that were previously done with dedicated hardware.
