Apple had all the incentives in the world to provide a transition plan and leave Intel behind. Also lots, and lots of practice with platform migrations, and they were transitioning to a hardware platform they were already selling in the billions.

Microsoft has exactly none of that. I'd be astonished to see RISC-V or ARM "take over" in the Windows world in less than another two decades, unless Intel's ongoing decline drags the entire X86 platform with it.

Still not quite it.

Apple had a transition plan because they wanted to drop Intel like a hot potato and switch to their own chips.

Microsoft has no particular dog in the processor fight, they don't make chips and aren't going to suddenly say "ok boys, we only going to support ARM"
