My understanding is Microsoft actually has some pretty cool and fast tech for this already: the Xbox 360 emulation on Xbox One.

No matter how good it gets, binary recompilation will always be slower than native code. And when the host CPU is already a very slow model like Qualcomm ARM, those effects stack.
That was PPC-on-amd64 emulation. I don't know much about hardware-assisted virtualization, but I guess that was easier than x86-on-ARM64?
