Apple announces Mac architecture transition from Intel to its own ARM chips, offers emulation story
Apple has just announced its plans to switch from Intel CPUs in Macs to silicon of its own design, based on the ARM architecture. This means that Apple is now designing its own chips for iOS devices and its Mac desktop and laptops. Apple said it will ship its first ARM Mac before the end of the year, and complete the Intel -> ARM transition within two years.
Apple will bring industry leading performance and performance-by-watt with its custom silicon. Apple's chips will combine custom CPU, GPU, SSD controller and many other components. The Apple silicon will include the Neural Engine for machine learning applications.

The Next Phase: Apple Lays Out Plans To Transition Macs from x86 to Apple SoCs
[From] an architecture standpoint, the timing of the transition is a bit of an odd one. As noted by our own Arm guru, Andrei Frumusanu, Arm is on the precipice of announcing the Arm v9 ISA, which will bring several notable additions to the ISA such as Scalable Vector Extension 2 (SVE2). So either Arm is about to announce v9, and Apple's A14 SoCs will be among the first to implement the new ISA, otherwise Apple will be setting the baseline for macOS-on-Arm as v8.2 and its NEON extensions fairly late into the ISA's lifecycle. This will be something worth keeping an eye on.
[...] [In] order to bridge the gap between Apple's current software ecosystem and where they want to be in a couple of years, Apple will once again be investing in a significant software compatibility layer in order to run current x86 applications on future Arm Macs. To be sure, Apple wants developers to recompile their applications to be native – and they are investing even more into the Xcode infrastructure to do just that – but some degree of x86 compatibility is still a necessity for now.
The cornerstone of this is the return of Rosetta, the PowerPC-to-x86 binary translation layer that Apple first used for the transition to x86 almost 15 years ago. Rosetta 2, as it's called, is designed to do the same thing for x86-to-Arm, translating x86 macOS binaries so that they can run on Arm Macs. Rosetta 2's principle mode of operation will be to translate binaries at install time.

This horse has been flogged so much that even the skeleton is disintegrating.
Linux covers exactly two use cases.
1. An experience that is so curated that the user doesn't even know they're using Linux (eg: Android, ChromeOS, etc)
2. You really really love dicking around with your computer, and/or are experienced with this kind of thing like sysadmins, etc.
While general usage at any given moment may well be fine, you will run into situations that require you to open a CLI or otherwise make an obscure conf file change in order to accomplish what you need. That has been reduced somewhat over the years, but it's still an issue. Hell, Gnome still won't let you add arbitrary applications to the application menu unless you open text editor and construct your own .desktop file from scratch. 'scuze me what now? Mac and Windows will literally let you do this with a single drag and drop operation.
Some things are so bloody idiotic that it leaves people incredulous. A great example is if you're on a laptop with discrete graphics, for example, you need to choose between battery saving integrated graphics or battery destroying discrete graphics, and you need to reboot/relogin (which for a consumer is basically the same thing) to change the setting. It's 2020 and you need to reboot to change your video chip. Something Windows and MacOS solved, what, 2 decades ago? And no, I don't care what the reasons are, no matter how justifiable you think they are.
The number of examples I could list are nearly endless. And nevermind the application ecosystem that is filled with software that, while they technically mark the necessary feature checkboxes, vary from unpolished, to difficult to use, to not fit for purpose for anything more than the simplest of use cases.
This is less of a problem for those of us that choose to swim in the deep end, but sometimes I just want to get my effing job done and *don't* want to go down a 4 hour irrelevant rabbit hole to change some obscure setting that is blocking my ability to do the task that I'm actually being paid to perform.
And this doesn't count blatant screw ups like when Ubuntu 19 shipped with a known broken crypto library that effectively disabled Active Directory integration, and then proceeded to never correct. The fix required you to install replacement libraries from some random 3rd party repo, which is completely unacceptable.
Meanwhile, the linux community seems to care FAR more about bullshit like theme choices and systemd, rather than truly important issues, like the fore-mentioned total lack of polish.

Waah waah waah. If you want someone to hold your hand, go pay for a consultant to integrate this free software complete strangers gave you out of the goodness of their hearts. You didn't pay for Ubuntu, right?

With respect to "like the fore-mentioned total lack of polish." - I still do stumble over polish issues in Windows and my friends with Macs stumble over them in Macs. It's not as often, and not as severe, but to me it's a 100 times as infuriating that companies with quite literally more than 1,000 times as much resources as the open source community still screws things up. No, a loosely connected group of volunteers that mostly gets zero money for their work on desktop apps can't match Microsoft, Google, or Apple. But they covered 80% of the gap with 0.01% of the resources - which makes me scream in frustration every time my work laptop hangs, or displays an error, or closes the File Explorer suddenly.

Sorry, but no. Once upon a time decades ago I liked fiddling with the OS and manipulating things. Now I just want it to work as I want, be reliable, and have the applications I need. Linux suits me fine. As it happens I use Mate, because that's the interface I got used to, and the others kept changing to be flashier. Gnome 2 was fine. So was KDE3. Actually, I think KDE3 was the best, but I don't fight city hall, so I use mate. And I use pretty much the default install, because I *don't* like fiddling with the OS, and it's pretty much what I want without messing around. But I'm not too particular, Gnome2 was fine with me, and so was KDE3. KDE4 became acceptable, but it did a bunch more stuff than I wanted. And I've stuck with mate and avoided fiddling with my OS (except apt-get update or install a new application) while MSWind has gone through 3 or 4 cycles of update/replace/revise. MSWind is the one that has required lots of fiddling with the OS and adjusting to new GUIs. And I haven't even looked at a Mac since OS10.4, so I can't say what it's been doing. As for MS, if someone asks for help I say "I don't do windows"...and that's the right answer, because I haven't touched it since slightly before 2000.
