Rosetta 2 on Mac looks impressive. I think pretty much all Linux and Windows users are hoping that a similarly impressive compatability layer will be developed for our platforms.
It’s hard not to be pessimistic though. Windows is generally a shitshow for this kind of thing (I don’t use Win 11 but Win 10 still has icons from the Windows 95 days!), and Linux is a Wild West with diverging priorities (look at the transition from Xorg to Wayland).
