I think you are missing one thing. This would not be a general purpose ISA designed for 3rd parties to develop and run things on it, this would be an ISA specific to Apple.<p>Apple has absolutely control on anything and everything that would run on this thing, I don&#x27;t think it is about paying licenses to Arm. When you have almost infinite money, in long term having a leaner&#x2F; faster &#x2F; more efficient custom ISA is better and lucrative than depending ARM or Intel for innovation. They can make it run existing applications with a transformation layer (already done by Nvidia&#x2F;Transmeta mentioned elsewhere in this thread) So, I don&#x27;t see why not.
