I'm just thinking about Windows. They are trying to do ARM again, but x86/64 is where they have stayed for compatibility reasons. At a certain point old software won't run on new Windows anyway, so it won't need hardware compatibility with older instructions to facilitate that. Eventually something will have to change, and is it less work for Intel to shift to ARM than to strip x86?
