Just because it's ubiquitous doesn't mean that it's good. Also, to be clear, x86 then became x86_64/amd64 which isn't the same architecture either. There will always be iterations and oddball architectures where something new can be learned and even reapplied to update x86. POWER, Sparc, etc. all taught new lessons.

Apple isn't scattering anything by running processors that run the same architecture as android and ios on phones. Most open source software can already be compiled for x86, arm, sparc, etc.
