Nebulous? When TSMC can no longer economically cram more transistors onto the dye, Apple will need other ways of increasing performance to keep the upgrade cash coming in. Apple previously co-developed PowerPC with Motorola (and IBM) for this very reason. At this time, Apple has all but kicked its third-party developers out of kernel space on its operating systems which will make for easy transition to future architectures. I would go so far as to speculate Apple is already designing proprietary RISC-V extensions and even their own FABs to produce them. One would expect such extensions to help Apple's systems execute Swift and ObjC better (faster and more securely) than general purpose processors and to optimize shared memory and fabric access between CPU, NPU and GPU cores.
