Just market share and applications.
I wouldn't mine a x86 core or two, but I don't think it will happen. What I'm hoping for is some kind of peripheral that would run x86/64 Windows.
Absent that, I need a computer to run x86 or my software vendors to port to M1. I don't see one of them doing that in the next decade. The other could do it easily but it's not in their current plans. So I use two machines now. I'd really like to not have to do that when mobile.
