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?

There can't be that many other people using it, but I'm using Rosetta2 to run the SML/NJ (https://www.smlnj.org/) implementation of Standard ML. The development team is working on a macOS/ARM64 backend, though.
