Human sensory systems evolved for survival rather than to accurately perceive the objective reality of the world.

“According to Darwin's theory, our sensory systems, eyes, ears, smell, touch, are not shaped to show us the truth. They were shaped to keep you alive long enough to reproduce successfully because seeing the truth takes too much time and energy. And so whatever reality is, it's utterly unlike anything”

Human perception is not a direct readout of the world but a controlled hallucination generated from inside-out predictions.

“We don't read out the world from the outside-in. We always actively construct it, actively generate it from the inside-out.”
