Good points all week. It’s like when I took my kids to Sesame Street something around 20 years ago and they had these gigantic (plastic, I think) appliances. One was a turntable, and I wondered how many kids knew what that was.
And to @fredd13 ‘s point, yes an actual camera is better but I can go to museums or the zoo and maybe see two cameras. Outside of that, everyone’s using their phone. The kid might never have seen one (or it never registered).
