As someone who can remember this never changing, that's a pretty steep slope...
Mind you, I would like to see them follow in Apple's footsteps on the train the M1 is creating. It certainly makes it FEEL like there is more runway down this path then Intel's, with caveats for potential hardware vulnerabilities like specter that simply haven't been found yet on Apple silicon to inhibit optimizations.

If you look at the trend, macOS is gaining worldwide market share while Windows is steadily dropping.
And macOS share in USA has already reached close to 25%.
Note that is for desktop PCs: many people don’t own a PC/laptop so the market share is far far lower than that, especially outside of rich countries. Microsoft is now primarily just business software?
