    Kenyen Coleman: Founder of DRIVETIME Movement

    Kenyen Coleman is the founder of DRIVETIME Movement. He’s a seventeen year-old junior in high school in the Chicagoland area with dreams of changing the state of transportation in America. In this episode, Kenyen shares what motivated him to start Drivetime Movement, explains the tools he has on his website, and we discuss the downsides of car dependency. Public transport is something that has long be of interest to me, and it was only after finding Kenyen’s work that I started to think more seriously about the role that cars play in our lifestyle. It often feels like, and it often is the case, that our cities and communities are more designed to serve the cars we get around in than us as humans. This is one thing I wish I would have discussed with Kenyen more specifically. To some extent, the solution to better transportation and less car-dependence is making public transportation and biking routes more accessible, which we discuss. But how we design cities, especially places that are getting redeveloped or where new housing is getting build, is equally if not more important to creating spaces that serve human well-being. So much, if not the majority, of houses in the US are built in neighborhoods that aren’t exactly designed for people, but designed for people who drive cars. What if instead there was greater collective focus on creating and shaping cities and neighborhoods that were better for walking and biking than driving. What if instead of neighborhoods with households where everyone has their own yard—which creates urban sprawl and car dependence, and incentivizes over use of pesticides and herbicides, and increases water use—there was more of a focus on developing housing with shared green spaces that bring people together; housing that’s less resource intensive, uses space efficiently, probably costs less, and makes driving less essential. If our lifestyle is how we live and exist in the world, our urban and suburban environments have an outsized impact on the space of possibilities for how we can live our lives. If we want to live healthy lives that involve movement, time outside, and socializing, we need to create and advocate for urban development and designs that make good living more attainable.

    Ultra-Processed America: What We're Really Eating (and Why It Matters)

    Google Gemini is getting really good and it really cooked on this one. This AI-generated podcast definitely isn’t perfect but it is super impressive. As far as I can tell there aren’t any factual inaccuracies, but disclaimer: I have not done a full fact-check on this. I did, however, revise the voice-to-text transcript to fix a few errors in case anyone here wants to listen with subtitles. I will say, based on my familiarity with this research topic, I’d be extremely surprised if there were any factual errors in this mini-pod. And the accuracy of Google Gemini is honestly super impressive (from my experience). This was the prompt I used to generate this: I'm planning a nutritional interventional study to improve dietary patterns in US participants. Please provide me a concise overview of descriptive statistics about US dietary patterns. I want to know about the consumption of ultra-processed foods, vegetables, fiber, calorie intake, and other such metrics and how these metric vary with income level, age, other demographics, and location, particularly proximity to grocery stores / food desert status. Here’s the full report created by Google Gemini Advanced Deep Research with 2.5 Pro. This has all the citation that were used to generate this podcast. Here are a couple timepoints I feel the need to comment on: 0:08 & 0:54 - Sounds like “NADS data” here, but that is not a thing. It is actually supposed to be NHANES that is stated here, short for National Health and Nutrition Examination Survey. 1:02 - *NOVA 3:44 - The man’s voice saying “That’s a pretty big difference” at this point made no sense because the numerical difference was not stated for the subject of interest (vegetable and fruit consumption). The “big difference” was the difference in income levels, which were arbitrarily chosen for the stat of focus i.e., that those at 350% the poverty level and above are “much more likely" to eat enough fruits and vegetables” than those at or below 130% of the poverty level. 3:48 - The “ok” is completely useless here; the AI should have asked, “What is NHANES?” at this spot. 4:10 to 4:40 - This section is very impressive in terms of quality of communication and how it seems like a real high production podcast, but then it ends with a sort of awkward/unnatural “ok,” “ok” from both of the AI voices and you’re reminded that this is 100% computer generated. 5:00 - The way the man’s vocal reaction here sounds so real 🤯 8:18 - There was a full blown matrix glitch at this point when the women’s voice says “It has.” Well, that didn’t sound right… at all.
