Artificial intelligence is all around us — even if we don’t realize it. Whether it’s in a self-driving car, a food delivery app, or our nation’s electrical grid, the rapid spread of AI and machine learning raises some big questions about security. How do we make sure AI-controlled systems are working as intended? And how do we protect vulnerable technologies from outside interference? Our guests from Pacific Northwest National Laboratory are working hard to answer those questions — and to get more scientists, engineers and tech leaders to start asking them.
