Scientists have been growing miniature brains in petri dishes using stem cells. These 'organoids' are a game-changer for medical research, as they can help develop new treatments and reduce the need for animal testing. However, the creation of these lab-grown brains raises a host of complex questions about consciousness and ethics.
Leading researcher Tal Sharf believes that organoids provide an unprecedented opportunity to study human cognitive capacity. He plans to use reinforcement learning techniques to discover how these miniature brains can respond to sensory inputs and solve problems. Sharf's team will also create benchmarks for organoid intelligence to understand how they learn and monitor them for the emergence of consciousness.
But is it possible that brain organoids could become conscious and experience pain? The answer remains unclear, but experts warn that such developments raise significant ethical questions. "These are just as exciting as the scientific and technological ones," said Hank Greely, director of the Center for Law and the Biosciences at Stanford University. "They range from the status of the human brain organoid and, ultimately, an organoid computational device β should they be treated as human tissue samples, as lab animals, as persons, or something else entirely?"
While it's unlikely that current organoids will experience consciousness, researchers are making rapid progress in understanding how they work. The creation of a whole-brain organoid, which represents only a small fraction of the brain's complexity, is a significant milestone. However, even this smaller model has shown promise as a valuable tool for studying neurological disorders.
One major advantage of using brain organoids over animal testing is that they don't experience pain. "It seems much better to me to risk potential organoid suffering over animals definitely suffering β and for little to no medical benefit in the case of neuropsychiatric research," said one expert.
But as researchers continue to push the boundaries of what's possible with brain organoids, a new question arises: can we use them to power computers? The blurred line between humans and machines raises concerns about AI consciousness and welfare. As experts warn, "get ready for renewed debate around AI consciousness, welfare, and maybe even personhood."
