Apple has invested billions to make a full transition to ARM.
I'd think that they would have to spend at least $50 billion or more to redesign all the Apple Silicon from the iPhone to the Mac Pro, rewrite 5 or 6 operating systems, and beg developers to recompile their apps.
It'd be a nightmare.
I think Apple will stay on ARM for at least 20 years...
Why just 20 years? This direction gives full control of a silicon roadmap. They can make it whatever they want or need. My guess is they have a more specific roadmap than even Intel or AMD at this point, as they're not commodity processors, but now engineered for a very specific purpose.
