A Polaroid is the best representation that can be made of a scene on Polaroid photo film. The lens, the paper, and other factors will always make the representation, to a degree, not real. That was the Samsung exec's point. It's a little disingenuous, though. The discussion shouldn't be about "real" vs "fake" it should be about "faithful" vs "misleading".
Add to that the fact that our brains run software that doesn't even try to faithfully store images and you have part of the reason that photos are, currently, more reliable than eye witnesses. That may be changing though.
Our brains are natural intelligence and perform natural learning. The results are even less reliable, predictable, and repeatable than the results provided by artificial intelligence.
As soon as you have sensors to capture something, you reproduce [what you’re seeing], and it doesn’t mean anything. There is no real picture.
A Polaroid photograph is a real picture, in the sense that it exists as a single, definitive, physical thing. Whether what it shows is real is a different question, though.
