My phone does local facial recognition! Upload photos to the cloud and Google photos does facial recognition of my individual pets! Stupid? Maybe. But the technology and research to pull that off is impressive. Smartphone cameras alone have pushed entire fields of research forward. Fancy 3d cameras are now used to save fractions of a second unlocking a phone! Try going back a decade and saying that 3d scanning would be a minor line item component that is shoved in a tiny notch above an OLED screen, a screen that has an image quality beyond anything available back then outside of a research lab. Oh then show them a 108 megapixel senor. Then finish it off with one of the TPUs that is yet another barely mentioned component in every phone.
