How many lives will be saved with the help of AI over the next decade? Reid and Aria sat down with Bill Gates to discuss his main areas of focus: climate change, energy, global health, and education—and how AI will help transform each of them. Taking a bird’s-eye view of society’s challenges, it’s easy to give in to pessimism. But as one of the most influential people in the world, Bill Gates has a unique perspective on how far humanity has come and what our potential—and timelines—for meaningful change really look like. He gets granular on everything from cows (5% of global emissions) to disease reduction and eradication (Guinea worm disease). At each turn, he has data at his fingertips to ground his beliefs. So, what current set of innovations is Bill most excited about? And what is realistically on the horizon for AI, climate change, energy, global health, and education?
