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?

The more important question is how many people buy a MacBook because they know they can run an x86 app if they have to.

Just because 0.1% of apps need a feature, the lack of it won't translate into only 0.1% of lost sales. People don't behave like that.

So the more important question is: how many people moved to ARM because they felt they don't need to worry about compatibility with existing use cases?
