Phones don’t have lights

Mark Zuckerberg has a new defense of the Ray-Ban Meta glasses: they're actually doing more to signal they're taking a photo than phones do. He's brought this up in at least two recent interviews, noting that the glasses have a light that comes on to signal when a photo is being taken, while phones do not. In one of the interviews, Joanna Stern notes that, while phones do not always emit a light, someone does have to hold a phone up in the air, which is itself pretty noticeable.
