>and not evolving through a knife fight between a few companies racing to extend it, like x86. Apple others you mention have an architecture license agreement with ARM. It means that they can develop their own cores but they must have full compliance with the ARM architecture. Does RISC-V require fully compliance? If not, RISC-V might be evolving through a knife fight between a few companies racing to extend it just like x86. When one company gets large market share, their extensions become de facto standards.
