The Globe’s Brian Bergstein will be joining Say More about once a month to host conversations about artificial intelligence, with the aim of asking big questions and getting past the hype. Artificial Intelligence is hard to define. It’s even harder to regulate. But without good regulation, the technology could do a lot of harm to innocent people. This week, Brian speaks to Columbia Professor Tim Wu, the father of “net neutrality,” about the best way to regulate AI and how to avoid the mistakes the government made with social media.
