Not sure. There are clearly some problems with the x86-64 ISA. If the world switches to ARM in the coming decade, that leaves Intel in a perilous position: no advantage in IP and no advantage in fabrication.
That will probably prompt other ARM vendors and certain PC manufacturers (Microsoft who already has the ARM based SQ chips, for instance) to further invest in similar products that chip away at Intel/AMD's lead and likely eventually overtake them.
