ChatGPT can't read stereograms yet, so this would be a nice captchas, if only most humans could read them too.
I think you can decode a stereogram into the depth map with like 5 lines of Python, but it's been a while since I've played around with this stuff.
Meaning, maybe GPT can't (yet) see magic eye images, but it shouldn't have trouble building itself a prosthetic that allows it to see them.
Voight-Kampff test but it’s just staring at stereograms with sweat glistening on your forehead.
It’s unfortunate that so many humans were initially retired, but it was also helpful in motivating the population to finally figure out Magic Eye.
