Honestly, I don't see how the rest of the industry can respond 100% to Apple right now. They can look at ARM and see the potential (as I'm sure they all are doing right now). But they won't have a means of getting there in the ways that Apple got there. The vertical integration between the OS and the SoC that Apple has won't be easy or even feasible for Microsoft or third parties to do. Not without changing the business model behind Windows PCs at a fundamental level.
All that being said, it was only during the Intel Mac era that a comparison between a Mac and a Windows PC wasn't an Apples and Oranges comparison. It was the same chips. Now, we're just back to the PowerPC era of comparing Mac to PC in that they're two different computers entirely.
Apple is certainly in an advantageous position from its years of planning ahead, its expertise in chip design and business model with tight control over hardware and software integration, I don't think it's insurmountable, but it's going to take years of effort and for the big players (
at least Microsoft and Nvidia (Arm), but better if more players, hardware and software are also on board) to come together and work hand in glove over that time. I would even go as far as to say Apple's biggest advantage isn't the chip hardware at all, but the fact Rosetta is so advanced, and that they're specifically running a
transition, not
adding Arm64 as an extra consideration for their software developers to maybe consider supporting if and when it gets to critical mass. This means Apple will probably have discontinued Rosetta and be powering ahead with native Arm64 Apps while on the Windows side it will still be pot luck whether you're getting a native Arm app, an emulated app that runs well, an emulated app that runs poorly, or an emulated app that doesn't run at all for years.
