I respectfully disagree. Why can't Intel/AMD make new flavor of chips & motherboards explicitly saying - it doesn't support x86 ISA. Then, wouldn't we address that problem?
Apple has an advantage here because they have both an integrated hardware and software platform they can control. If only Intel did the same they'd be relying on Microsoft to provide a translation layer for their chips and that'd be unlikely unless they paid up and Microsoft dared to stray from its traditional course.
