“To put it bluntly,” wrote Bill and Melinda Gates in their foundation’s annual Goalkeepers Report, “decades of stunning progress in the fight against poverty and disease may be on the verge of stalling. This is because the poorest parts of the world are growing faster than everywhere else; more babies are being born in the places where it’s hardest to lead a healthy and productive life.” There is no topic in the philanthropic world more fraught than population growth. The history of efforts to analyze and address it is filled with bad predictions and cruel solutions. The Gateses, though, are trying to take a different approach to the issue. Rather than seeing a population problem in the demographic projections, they’re framing it as a poverty problem — and, for that matter, an opportunity. In this conversation, I talk with Bill Gates about the report and about much more: the geographic and political forces that have held African development back, whether economic growth brings political freedom, the risks posed by artificial intelligence, and how we should weigh future human lives and current animal suffering. This conversation also marks the launch of a new Vox podcast and section, Future Perfect, which focuses on evidence-based ways to make the world a better place. You can find the section at Vox.com, and you can find the podcast, which is hosted by my colleague and friend Dylan Matthews, wherever you get your podcasts. Enjoy!
