the CPU architecture is not as directly tied to the software as it once was
Yeah it used to be that emulating anything all would be slow as balls. These days, as long as you have a native browser you're halfway there, then 90% of native software will emulate without the user noticing since it doesn't need much power at all, and you just need to entice stuff that really needs power (Photoshop etc), half of which is already ARM-ready since it supports Macs.
The big wrench in switching to ARM will be games. Game developers are very stubborn, see how all games stopped working on Mac when Apple dropped 32-bit support, even though no Macs have been 32-bit for a decade.
Be careful in trying to interpret year over year statistics. Last year was huge for Apple as if you look at Q3 2022 then Apple increased sales 10% while the rest of the PC market dropped a massive 18%.
You're saying "since switching from x86 to ARM apples sales are down! see it was a bad idea!" but actually they have been way way up and are just finally getting inline with the sales decline the rest of the PC industry has had after the covid work from home rush ended.
