Intel is gonna be in deep trouble in couple of years. They are the PowerPC of modern era. IDK what held them back from reimagining the architecture for less power hungry processors and tooling. With Mac mainstream switching to ARM and Microsoft doing something similar, I think within next 5 - 10 years ARM is gonna take over Intel architecture in general.
Apple is using their own cores, Google is using thei own cores, Amazon is using their own cores, I bet Microsoft is next... Eventually these new chips will hit the desktop and then we'll see the x86 start to sink.
Apple are the leaders in terms of arm microarchitecture.
