It probably won't. Macs already had compatibility issues with things made for PCs (e.g. Linux), so I doubt widening that gap further will change much. Then again, I tend to be continuously surprised at what kind of cues tech companies take from Apple. Like, it didn't surprise me at all when iPhone abandoned headphone jacks, but I was absolutely baffled when other phone companies followed suit.
If anything breaks the x86 monopoly, I really hope it's something open source like RISC-V and not just companies trying to copy Apple's dumb bullshit. Who am I kidding though, that's not gonna be the case.
