The Pentium 4 to Core 2 Duo leap was based on architecture, not fab tech. It was a very significant shift in chip design philosophy. Intel being ahead in fab tech didn't hurt, but it's far from their only strength. There's no reason to believe M1 will open any sort of gates for Arm on PC. It's not like other Arm CPUs will be running Mac OS, or M1s will be running Windows. The whole pre-Intel period for Mac OS didn't do anything to diminish x86 on the desktop. Now, Chromebooks are something of an argument for ARM on the desktop, as they at least seem to provide identical behavior regardless of ISA, but they aren't putting up the necessary numbers quite yet. x86 still owns PC gaming, and has a pretty solid hold on console gaming. I'm not going to be worried at all for Intel until that shifts too.
