I want to know what this does to Docker/HyperKit. If we lose the ability to run Docker on ARM macs, that will mean hundreds of mac users in IT at my company alone will migrate to something else. I would expect this would bork a large percentage of engineers developing for any modern cloud tech stack. In my case, I'll go back to linux. I enjoy linux, but being pushed out of the glistening walled garden of the Apple ecosystem on my laptop is going to sting a lot. I know Apple makes a lot more money from their non-pro market, but it sucks how they've been systematically dismantling so many of their offerings tailored towards pros.
You can certainly run Docker on ARM, but similarly to Docker on x86, it will use the ARM-Linux kernel, so your images will need to based on ARM-Linux.
