Personal computing icon turned philanthropist Bill Gates has finally made it to the Nerdist! Chris, Matt, and Jonah caught up with Bill in Seattle to talk about how the digital revolution is turning your phone into a debit card, Bill’s earliest memories of the computer revolution, and how difficult it is to get a whole world behind eradicating disease. They also discuss the Bill and Melinda Gates Foundation and this year’s annual Gates Foundation Letter! And as a special add-on to the podcast this week, Chris and crew spoke with Jay Wenger – director of the Gates Foundation’s polio eradication efforts and former CDC epidemiologist – and Julie Sunderland, director of program-related investments at the foundation. They talk about why improving global health is much more complicated than just throwing money at a problem, and if the former epidemiologist is afraid of zombies.
