Sal Khan is the founder and CEO of Khan Academy. Sal’s problem is this: How do you design an AI that can give students the kind of benefits they’d get from working with a human tutor?
Earlier this year, Khan Academy launched Khanmigo, an AI tutor built on top of GPT4.  The idea is to use AI to give more kids access to one-on-one tutoring, and help human teachers with their work as well. See omnystudio.com/listener for privacy information.

Every week on What’s Your Problem, entrepreneurs and engineers talk about the future they’re trying to build – and the problems they have to solve to get there.

How do you take a drone delivery service you’ve built in Rwanda and make it work in North Carolina? How do you convince people to buy a house on the Internet? How do you sell thousands of dog ramps to weiner dogs all across America when a pandemic breaks the global supply chain? 

Hosted by former Planet Money host Jacob Goldstein, What’s Your Problem helps listeners understand the problems really smart people are trying to solve right now.

Imagine picking up your phone and ordering something from Walmart. Fifteen minutes later, a drone hovers over your yard, lowers your order down to you, and zips away. Adam Woodworth wants this to be so boring you don't even notice. He’s the CEO of Wing, a drone delivery company. His problem is this: How do you turn a flashy idea like a delivery drone into something as ubiquitous as a shopping cart? See omnystudio.com/listener for privacy information.

Designing a Drone That Delivers

Psychedelics are going mainstream. The FDA has approved ketamine for certain patients with depression, and may soon approve MDMA for post-traumatic stress disorder (PTSD). But a fundamental question remains unclear: How do psychedelics work?
Gul Dolen is a professor of psychology and neuroscience at UC Berkeley. In a series of experiments, Gul has found evidence of a common mechanism that a wide range of psychedelics use to affect the brain. If Gul is correct, these drugs may be useful not only for people suffering from mental illness, but also for people dealing with neurological problems like strokes.
