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.

For games on intel macs they had fallback of BootCamp so combined with not really caring about games outside of random bursts like support for Unity, they were fine telling people to run windows. (ironically, the only Mac I owned ran faster under windows than under macOS...)
