Imagine basilisks specifically designed to crash these algorithms: abstract-blocks-of-black-and-white-for-heads that, like the QR codes of old, carry a hidden message in their patterning, only it’s a payload, a virus that shreds the system of anyone who tries to capture it on camera, the natural evolution of anti-face-detection camouflage. Imagine things that don’t even have faces, that don’t have an equivalent and easily-cataloguable part; people who deliberately wear mass-produced, identical android bodies, the Guy Fawkes masks of the future.
It’s a thing! Turns out, people would rather not look stupid than not be caught by facial recognition.
Somehow they look exactly like you would expect cyperpunk protagonists trying to avoid detection by facial recognition software to look.
