Assuming they build the new Macs around the SoC - does this effectively kill any hope of dual boot support for Linux/Windows etc. It's not just the ARM processor in there, those SoCs have a bunch of Apple proprietary stuff (inc. GPU) that I very much doubt will have open source drivers. I know the 2016-2020 macs are pretty much terrible for Linux anyway due to hardware issues (audio, keyboard, wifi....) so it's no surprise there - but I fear this shift to "Apple Silicon" effectively kills it.
