A highly optimized brain doesn’t bother wasting time on getting fine details like this correct, it’s too slow and will lead you to getting killed in situations where a rough approximation of what you are seeing is good enough. People have to focus very hard to turn off the optimizations and see what is really going on, some can’t do it at all. Some people seem to be able to see the smooth linear motion by default, perhaps descendants of those who lived in simpler environments.
Why do you think it takes more time and brain power to see the rectangles and pigeons correctly (smooth movement)? It was instantaneous and natural for me. I’m not convinced by your logic. It doesn’t seem like a disadvantage for a brain to naturally register the image correctly rather than being fooled by an illusion, especially when it takes zero effort.
(I think people like to call this “steel man” or whatever but just generally applying a charitable interpretation…) I think their take on optimization is about falsehoods about reality that our brains assimilate to make functioning or survival possible under certain circumstances, like perceiving magenta as not-green or being able to observe a field of grass without being hyper aware of each blade of grass within it.
All of which is good insofar as it actually serves us, but it’s really weird to me to frame it so absolutely. It’s not an optimization if it doesn’t serve us and we’re just misperceiving reality for no purpose, and there’s nothing wrong with you or anyone else who doesn’t. If anything it’s just… “wow, electrified meat evolved to be conscious is really wacky and super subjective!”
