If the 2027 AirPods and AI pin/pendant, both expected to come with cameras (or at least an optimally placed microphone bug), are anything to go by: "the cameras ... are not designed for taking photos and videos, and will instead send information about the wearer's surroundings [including any others in it] to Siri."

Phew... I'm soo relieved the data is just being fed straight to Siri.
