I think the best counter response to the “think about how awkward the dad must have been taking that birthday photo wearing one of those” is a reminder of the 90s VHS camcorder era. Dads will Dad no matter the era and the iPhone era is the weird less clunky exception compared to the 90s camcorder (or 80s Polaroid or 1880s Daguerreotype).

Though I think a different thing that the keynote briefly mentioned but I think a lot of people missed it: iPhones today already capture a bunch of depth information in certain types of Live photos. You can do basic stereography with the existing camera hardware on recent iPhones. (Even Meta knows this: you see interesting parallax effects when certain iPhone friends post their photos to Facebook because that’s FB having fun with available depth information.)

iPhone has already been adding the sensing hardware for things like those sorts of photos. (How’s that for long term planning synergy?)
