The point where you suggested that x86 PCs are "open systems" (listing it next to "Linux" of all things!) I realized that you don't get it. We are where we are with Intel ripping off the consumers and companies alike exactly because nobody realized that x86 is everything but open.

A similar mistake is about to happen, but luckily on the software side where losses can be cut quick and mistakes can be reversed easier -- though many will suffer when they have to reimplement their precious library from ground up because they did (or could) not take into account the fact that CUDA is as proprietary as it gets.

AMD has no CUDA compiler BTW. And CUDA is not a programming language FYI. ;)

But accepting a monopoly standard guarantees loss of freedom and rules out any future prospect of legitimate competition.
