If you’ve tried AI and felt underwhelmed — or if the constant pressure to “just play around with it” makes you want to throw your laptop across the room — you’re not alone. But according to Max Mullen, co-founder of Instacart and one of the most practical thinkers on this technology, you might be closer to becoming an AI expert than you realize. In this episode, Max makes the case that expertise with AI isn’t about taking a course or spending your weekend trying to learn how to use it. Max talks about how to use AI to solve real problems, why you want to try it more than once, and argues that building a relationship with the tool is the key to getting better and faster results. This is the episode for anyone who’s skeptical, behind, or just exhausted by the hype.

Electric vehicles have a surprisingly long history. Battery-powered cars have existed since 1881. So why did the world choose to spend over a century investing in fossil fuels? Sherrell explores this question with a talk from engineer Doreen Orishaba. Doreen built Africa's first electric vehicle and now runs 100+ electric buses across East Africa. Her success proves that the countries that did not inherit a broken infrastructure may be best positioned to build what comes next. Then digs deeper into the background of electric cars in a TED-ED lesson from Daniel Sperling and Gil Tal.

Algorithms and AI don’t show us reality, but that doesn’t stop people from treating ChatGPT and online bots as our personalized therapists, travel planners, and editors. In this episode, Sherrell is sharing two talks on how AI is changing the way we’re influenced.

From local parks to the Amazon rainforest, trees provide shade and shelters for humans, animals, insects, and many other living creatures. They’re the lungs of our planets, but they’re being threatened by deforestation.

Is it effective to engage with politics on social media — and what does it take to make actual change? Katherine Cross is a researcher on online harassment and the author of Log Off: Why Posting and Politics (Almost) Never Mix. She shares why she believes social media is “anti-political” and how virtual engagement will not achieve the necessary political work for us. Katherine and Chris also discuss the limitations of short-form content in conveying decades of geopolitical strife, why our lives would be better off without social media, and the guardrails platforms could utilize to help users engage with posts critically and to slow down viral misinformation.
