Jonathan Zittrain, Director of the Berkman Klein Center for Internet and Society at Harvard University, discusses what that would look like for platforms like Facebook.Why Computer Science Students Need Mandatory EthicsShannon Vallor teaches ethics and emerging technology at Santa Clara University. Her classes typically have lots of computer science and engineering students in them, and it may be the only real ethical training they get. These days, they are clamouring for more ethics education.Why Canadian universities need to teach computer science ethicsBy and large, computer science programs in Canada don't require students to take ethics courses. As we hurtle into an era of artificial intelligence, Catherine Stinson argues we need to make ethics mandatory in university.Neural networks that power AI systems largely came from CanadaCanada has become a centre for AI research thanks work being done here on neural networks, which use some of the ideas from neuroscience to help computers learn. One of the researchers behind these systems is Universite de Montreal professor, Yoshua Bengio. In a sit down with Spark host Nora Young, Bengio explains how the research developed, where it is going, and some of the dangers AI could pose.
