But even if AI does achieve this technical milestone, one neuroscientist says it still won’t rival the complexity of the brain, because ultimately AI will still lack consciousness. AI becomes superhuman and that’s the moment when the lights come and AI is suddenly aware. That’s because this “controlled hallucination” theory relies on our biological bodies, something AI simply doesn't have. Particular among these are collections of stem cells known as brain organoids, which are designed to mimic human brain function. In many ways, Seth sees organoids as a more compelling candidate for investigating consciousness than the world of ever-advancing AI.
