Designing these processors to emulate x86 is not sustainable in the long run. Microsoft will most likely make an updated SDK (Project Voltera) using the snapdragon elite processor, but software developers can utilize the current Project Voltera SDK kit to get the groundwork started at least for apps. If they do that on an old Qualcomm processor, the elite will run it blazing fast.
With Build 2024, i hope MSFT will develop updated tools and API's-and even utilize generative AI to help coders make native and optimized code for both x86 and ARM in the easiest to way possible. They have already incorporated Xamarin into visual studio (one base code for windows, android, and iOS), so this shouldn't be that hard.
They also need to optimize pen support for stand alone windows tablets/laptops/all in one PC's utilizing GPU/NPU (since its getting beefier now instead of those shitty iGPU's from intel), with low latency/lag and close to 1:1 input/touch to response.
