> One interesting question I think is outstanding - from parsing the video carefully, it seems to me that devs are going to want ARM linux virtualized, vs AMD64. I’m not highly conversant with ARM linux, but in my mind I imagine it’s still largely a second class citizen — I wonder if systems developers will get on board, deal with slower / higher battery draw intel virtualization, or move on from Apple.

Somewhat ironically, I think it's mostly the languages trying to be safer alternatives to C that are most behind on supporting ARM.

I've done a little bit of Lisp development on my Raspberry Pi (with SBCL and Emacs/Slime), and in most cases I don't have to change anything moving between my AMD64/Linux desktop, Intel/OSX MBP, and ARM64/Linux Raspberry Pi. And that's even when using CFFI bindings to C libraries.

I'm not sure SBCL's ARM backend is at the same level as the x86 backends, but it works well, and there's on going work on it.
