I'm not surprised that there are loads of attacks like this. On QI recently (a TV prog in the UK) a series of images were presented showing just how asymmetric our faces are. Try taking a photo of your face or someone you know with as near symmetric lighting etc as you can manage. Now cut the image vertically and mirror each half and compare visually. Frightening isn't it? Now add fancy patterns that can be hidden within an image that eyes miss but algos don't. AI does not see the way you and I do. It can't. AI can be twiddled constantly to get it into line with what we perceive and we could call that evolution. In 200M years it might be quite good. I suspect that progress will be faster than that but those machines can't type on a keyboard balanced on its knee whilst drinking wine and admiring a landscape with a setting sun whilst worrying about how to shop tomorrow, now masks are compulsory. What's the SO up to? The TV is showing crap and a new Netflix series is available but I can't be arsed ... The march of our robot overlords is unlikely soon.

Why cut and mirror? Can't you just mirror? Wouldn't this be the same as just looking at someone's face in the mirror?

  No, he's not saying to flip, he's saying that the left and right halves of your face aren't symmetrical, and it's very uncanny valley if you view a portrait of a person with symmetrical left and right halves. https://www.google.com/search?q=symmetrical+left+and+right+face&client=safari&rls=en&sxsrf=ALeKk00H3BYWmHtUZ46V1vuEYpAursuDRw:1595483483459&source=lnms&tbm=isch&sa=X&ved=2ahUKEwig7JqS1-LqAhVFiYsKHegKCk4Q_AUoAXoECA0QAw&biw=1151&bih=816 https://www.google.com/search?q=symmetrical+left+and+right+f...

    Oh, I see, thanks.

    Almost all of these (including the example on QI) are just poor editing. There are some examples in those results where it's been done properly, with symmetrical lighting, and the results look... almost exactly the same as the original. Unsurprisingly.
