This method is basically just fuzzing with a really efficient method to do it quickly. But in theory you could try every possible set of inputs into the human eye, and it&#x27;s quite possible you would find images like this, where only slight changes to the inputs cause entirely different outputs.<p>But we can&#x27;t try every possible set of inputs to human eyes. So we don&#x27;t actually know how fragile human brains are. I suspect that brains use similar tricks to artificial neural networks, and learn similar functions.
