I think that they will get things in order by the time the consumer hardware is released. I'm sure that they will have virtualization support and Electron will be working as well. My main concern is the Rosetta2 performance and what that will look like on the final products. Hopefully with some of the virtualization support, it will be faster, but it's a wait and see I suppose.
I think that we could really see an era where Ruby on Rails development starts moving away from Apple. Windows/Docker with WSL2 is very viable today and Linux is always pretty solid. macOS had a lot of support with it's spit and polish, but what good is it if Nokogiri takes an hour to install. However, I do believe that it is too quick to judge and we need to see what things are like when the official consumer hardware is released. Hopefully Apple does do a trade-in on the DTK like they did the last time with the iMac DTK.
