What is intelligence? Can artificial intelligence get more intelligent than humans? Does a high level of biological intelligence require a complex brain? In his new book “Birth of Intelligence”, MBI Professor Daeyeol Lee tackles these pressing fundamental issues. To better prepare for future society and its technology, it is essential to understand the biological root and limits of human intelligence. After systematically reviewing biological and computational underpinnings of decision making and intelligent behaviors, he proposes that true intelligence requires life.
