Super interesting. Putting my PM hat on, I wonder: how many x86 apps on Apple still benefit from this much performance? What's the coverage? The switch to M1 happened 4 years ago, so the software was designed for hardware nearly half a decade old.

Excellent engineering and nice that it was built properly. Is this something that Linux / Wine / the Steam compatibility layer already benefit from?

Games. So many games.

Also, x86 containers.

Then again games didn't stop Apple from dropping x86-32 support, which nuked half of the Mac Steam library. It wouldn't be out of character for them to drop x86-64 support and nuke the rest which haven't been updated to native ARM.

Rosetta supports it at least. You can run Linux 32-bit games!
