Hardware

This video entirely misses the point. The x86 emulator (technically a transpiler) is just a part of equation. The important thing is that Apple emulates some of the x86 behavior in hardware. And it’s not something a software emulator can do, at least not without significant performance problems. As far as I know, current Windows on ARM ”cheats” by pretending memory order is not a problem. This works until it doesn’t, as some software will crash or produce incorrect results. Microsoft has different emulation levels as described in their support docs, each with those come with increasing performance cost. As Qualcomm did not announce technology to safely emulate x86, I assume they don’t have it. Which would mean the same clusterfuck of crashing and incompatible software Windows on ARM has to deal with now.
