Microsoft uses the word emulation in their documentation but by most modern definitions what they are doing is binary translation or recompilation. Emulation is an old concept that has changed definitions over time. Both x86 and x86-64 are being translated. Preview versions of Windows 10 had x64 compatibility but that never shipped in a stable version of Windows 10 and now has been moved to Windows 11. You can read about it here.
Learn how emulation for x86 apps makes the rich ecosystem of existing Win32 apps available on ARM devices.

To wit: (emphasis mine)
This
MIT presentation defines emulation as "
OS software interprets instructions at run-time" and binary translation as "
convert at install and/or load time". I believe these are the current accepted definitions.
Unless you can provide more documentation showing that Intel is still threatening Apple, Microsoft, or Qualcomm, I don't think there is much more to discuss. Please feel free to link to something concrete if you have it.
