By "dust settled" I don't mean that the technology "exists" -- but rather that feature development has slowed down and most products have stabilized as feature complete and mature.

The on-device ML models that are being used by Google and Apple are both quite new and in active development.

Many of Apple's most successful products have shipped years or even a decade after their competitors. They have tried using first-mover advantage in the past but typically fail when using that strategy.
