When surveillance tech is marketed as jewelry:
"Tab is a small, circular pendant that hangs around your neck and listens to you and those around you."
"Rewind Pendant is a wearable that captures what you say and hear in the real world" (and makes it searchable with a "personalized AI")
"The Humane AI pin has indicated that the pin will have always-on listening capabilities."
Is this really the future most consumers want?
