They are developing smart glasses for this purpose to compete with Meta, as well as other moonshots. No one is for sure what the platform will be; maybe it will just be the iPhone still, but my inclination at the moment is glasses. The only barrier to glasses is public resistance at this point-- but I don't see that preventing their rollout and eventual acceptance.
Additionally, it seems relevant to point out that they are the number one choice in consumer grade hardware for inference. So that is direct evidence of their seriousness and preparedness.
