> Until one day you realize that you can run an x86 program on a 64 bit CPU (but fortunately, this isn't done through “emulation” proper either).

It's reasonable to call that emulation if there's a separate layer for it translating to/from x86-64, rather than the hardware specifically supporting -32. My CPU isn't doing that cause I'm not running 32-bit software on macOS.
