Nah. Apple doesn't have incentive to provide any more dev power. It will keep things locked down and charge people for Apple branded software products. That has been their business for the past decade.
I think there's always been a tension at Apple between keeping everything as locked down as possible and opening up parts because they need the developer driven app ecosystem. My prediction is Neural Engine is going to become more useful to third party developers. I could be wrong
Apple's AI strategy is to put inference (and longer term even learning) on edge devices...only for Apple stuff.
There is a big difference. ANE right now is next to useless for anything not Apple.
