I'm excited for the day that I can easily install SteamOS (the modern one that runs on the Steamdeck) on an M2 Mac mini for an insanely powered "Steam console" for my living room TV.
Things are certainly looking better than they did a couple years ago, but getting ARM to run x86 code faster-than-native is an uphill battle. Maybe even an impossible one, but I've been surprised before (like with DXVK).
