Recent employee unrest at Google was stirred, in part, by their concerns about the company's research into, and implementation of, artificial intelligence (AI) technologies. Google has been making significant advances in AI, and it's not alone. AI is now a focus of a range of enterprises, and it’s becoming an essential part of a growing number of products and services. Google's employees threw a spotlight on what has been called "ethical AI.” John K. Waters sorts out the evolving definition of this concept in a conversation with Anupam Datta, Professor of Electrical and Computer Engineering at Carnegie Mellon University. Datta is also the director of the school’s Accountable Systems Lab, and co-founder of a startup called Truera, which grew out of his work on explainable AI.
