For me, this is the end not just of hackintoshing but of Apple. It's absolutely possible that at some point in the future there may be some kind of Mac Emulator for either Intel or some generic ARM board, but it will be far from usable for work. There will be a custom GPU, T2, Crypto, AI and more designs on the chip & co-processors in Macs. It may be possible to emulate some in software, but nowhere near stable, fast and usable for work.
I loved macOS while it lasted and I hate Windows, but not at all costs. Not being able to repair and extend my own hardware and especially not being able to boot into Windows for an occasional game, some development stuff or specialized software not available for Macs is a no-go.
It may be great for some people to run the next Flappy Bird now natively on their mac or try to figure out how to use Cubasis without touch mechanics, but that's not me. If I wanted an iPhone with a big screen, I would plug an iPhone into a big screen.
I'll stay until the lights go off, but that may come sooner than some might think. When new updates for software will only be released for ARM Macs or show more bugs than usual for Intel CPUs because developers don't care anymore and/or developing and fixing bugs for two platforms is just too much work, I'm out of here.
There is simply no use for me for an ARM Mac at all. That's like going back to 2008 and start all over again while everyone else lives and works in the 2020's.
My last - tiny - hope is that people just won't buy ARM Macs. If they don't sell, Apple may think again about this move. But even this tiny hope would just mean the next years are wasted. So I could probably move back to ugly Windows & Android right away as well. Maybe it's time to buy a new Nvidia GPU then, I never liked the Vega.
