    The following article suggests why it is NOT going to happen:
    I think a better tense for that sentence is that "The following article suggested why it is NOT..." The article is from 2012 and 7 years is a lifetime in computer terms. The A-series chips have come a long way since then and the Intel chips have NOT made much headway in the smartphone universe, as the article stated it would do.

    Personally, I think Apple will go to ARM processors, if only to ave greater control over the pipeline. I also suspect a certain percentage of users will then abandon Apple because they won't like the change. But Apple has made CPU changes before, so they know the impact and how to address it. Maybe a Rosetta for the ARM chip will be provided for a while to reduce the impact?

    From what I've read, good x86 emulators for ARM have been around for decades. So the transition should be seamless.

    Apparently Apple plans to merge iOS, macOS, and iPadOS so that all apps will run on all platforms. (They are basically the same codebase already.)

    The big impetus for this is twofold:
    1) Intel's x86 chips have hit a wall, much as the PowerPC did, while ARM still has quite a bit of headroom for more performance per watt.

    2) Intel charges Apple hundreds of dollars per processor. If Apple makes their own processors, that price will drop significantly. It may lead to much lower prices for Apple's devices.

    Yep on all of those, Randy. The one "con" article, in addition to being old, was assuming that some breakthrough was coming from Intel (didn't happen) and that ARM growth would not catch up to Intel (it did). I used to need Windows for one application so I was leery of Apple ditching Intel as that would make Windows emulation very, very hard or very, very slow (an emulation running in an emulation). But that one need has receded, so now I'm ok with ARM as long as Apple gives time to make the transition like they did with the PowerPC/Intel transition.

    But Apple is pretty smart and they've probably got it all figured out to make the change as problem-free as they can.

    The fact that Apple will move to ARM processors has been known for quite some time. Apple already uses an ARM chip in the iMac Pro, 2018 Mini, and the newer MacBook Pros. It's called the "T2". As for X86 emulators, anytime you add a layer of emulation, it results in a reduction of performance.

    I personally don't believe Apple will switch to an ARM processor all at once. It's definitely coming but probably in steps.

    Yes, that's what some of the articles I cited said. They expect to see ARM MacBooks (with the ARM processor being the primary processor, not a secondary processor as they are now) next year, with ARM processors coming to other Macs later.

    I would imagine it would be awkward, to say the least, to have a mix of processors in new machines. Two different versions of the OS, every App, both Apple and third party, etc. It would be better to have a clean cut. Old machine-Intel. New machine-ARM. Wait three years, abandon Intel in the OS.

    If Apple history repeats, there will be several years or more for the changeover to take place. It's not like Apple hasn't done this before: Motorola - PPC - Intel - ARM?
