Ethical AI ambitiously hoping to have AI learn ethical behavior by itself, such as the case with AI in autonomous self-driving cars
Aristotle famously stated that educating the mind without educating the heart is no education at all.
You could interpret that insightful remark to suggest that learning about ethics and moral behavior is keenly vital for humankind. In the classic nature versus nurture debate, one must ask how much of our ethical mores are instinctively native while how much is learned over the course of our living days. Toddlers are observant of fellow humans and presumably glean their ethical foundations based on what they see and hear. The same can be said of teenagers. For open-minded adults, they too will continue to adjust and progress in their ethical thinking as a result of experiencing the everyday world.
