Sean Carroll argues that the boundary between natural and artificial intelligence is blurring. He references 18th-century French philosopher Julien de La Mettrie, who asserted that humans are essentially thinking machines. Carroll suggests that modern physics and neuroscience support this view. He notes that artificial intelligence development has been challenging because it requires an integration of hardware and software, similar to how the human brain functions. Advances in brain-computer interfaces are breaking down barriers between human cognition and machines, offering the potential for enhanced human abilities. Carroll concludes that as technology continues to augment human cognition, the challenge will be to use these new capabilities wisely.
