Neurotypical exists. Neurodivergent is the more “leftist” or scientific term for what they mean.

But what’s the normal amount? At what point does it become evidence of neurodiversity?

Everytime I see these posts I experience this. Can somebody who definitely is not autistic please confirm that this doesn’t occur in their life?

What a stupid piece. You don’t need anything quantum to recognize optical illusions. An optical illusion as they talk about it means that an image could be recognized as two things. This can be done by just adding some noise to the image. Sometimes it gets recognized as one thing and sometimes like another, just like humans would.
