Imagine it becomes easier to run Windows x86 programs on Linux, than on Windows. And I won’t be surprised at all if performance is better.
Imagine if THAT becomes Linux’ killer feature.
A more lightweight system without the crazy system requirements, certain systems more stable and easier to get into for gaming, no ads and no spyware out of the box, no extra cruft nobody needs out of the box, and better support for x86 emulation on ARM.
Now THAT is a checklist to getting people interested.
There is also the free of charge aspect, but I’m not sure how appealing that would be, with Windows being bundled in.
It is crazy how many highly skilled people put a lot of free work into pushing Linux forward, because of „let’s see, if we can get this thing working!”
I might be very mistaken, but I don’t think QEMU can link mixed-architecture dependencies. Box86 can run an x86 game on ARM and link ARM-native shared objects for OpenGL, thus emulating strictly only what’s not available as native.
