Why doesn't `Texture2D` expose its pixel data?

Texture data is almost always copied to video memory (VRAM) by the graphics driver when the texture is initialized, for performance reasons. This makes texture fetches by the shaders running on the GPU significantly faster; you would definitely not be happy if every texture cache miss had to fetch the missing data over the PCIe bus!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
