It is clear that any further investments in X86 based architecture will bring diminishing results. With modern OS and app stores, the transition to a new CPU architecture is much easier, since the app stores themselves compile the source code provided by developers. The end user mostly does not care if it is an X86 based Intel, AMD, or a RISC type of a processor running the system.
I expect the private consumers to move first to ARM, followed eventually by datacenter clients. Expect Intel to be half gone by 2023, if it insists on not making the switch to ARM.
