> AArch32 is irrelevant in the context of the M1.

Is it? It's not like Apple moving MacBooks to M1 happened in a vacuum. M1 is only the latest in a whole series of Apple ARM chips, about half of which were non-aarch64.

That context actually seems extremely relevant to me; it demonstrates that Apple is not just jumping wholesale to a brand new architecture. They migrated the way large companies usually do: slowly, incrementally, testing the waters as they go. And aarch64 was absolutely not involved in the formative stages (which are arguably the most important bits) of that process. It hadn't even come into existence yet when Apple released their first product based on Apple Silicon. Heck, you can make a case that the process's roots go way back before Apple Silicon, all the way back to ~1990, when Apple first shipped the Newton.

Note, too, that the person I was originally replying to didn't say "M1", they said "Apple Silicon." In the interest of leaving the goalpost in one place, I followed that precedent.

Your point now seems to be that M1 is the latest in a line of processors with ISAs designed by Arm limited. I'll agree with that and leave it there.
