The freeCodeCamp Podcast

Today Quincy Larson interviews Shawn Wang. He's a software engineer, founder of the AI Engineer conference, and host of the Latent Space podcast focused on applying the latest models toward getting work done.
We talk about:
- How even if LLMs plateau, there will be still paths to better output through surrounding harness code
- And three big areas researchers are exploring to further improve model performance: World Models, Multi-modality, and Embodied AI
- Which skills Shawn thinks are most important for developers going forward
- And why Shawn thinks you should switch your own self teaching from "just-in-time learning" to "just-in-case learning"

1. I spent three days at the San Francisco Palace of Fine Arts recording a documentary about the world's largest collegiate hackathon. More than 3,000 student developers participated in this year's UC Berkeley Cal Hacks hackathon. Over the course of 36 hours, they built a broad array of projects, then demo'd them to judges from industry. I now present to you the finished documentary. I hope you find it both enjoyable and inspiring. (80-minute documentary): https://www.freecodecamp.org/news/inside-cal-hacks-2025-36-hours-at-the-worlds-largest-collegiate-hackathon/

5. Our song of the week: Supergroup The Power Station's 1985 hit "Some Like it Hot". This entire album features incredible drumming by Chic drummer Tony Thompson. And with Bass and Guitars by Duran Duran's John Taylor and Andy Taylor, the whole song has insane groove. 80s icon Robert Palmer sings and brings the texture. The guy reportedly smoked 60 cigarettes a day and paid the price a few years later, but man is his voice golden on this recording. Fun fact: Duran Duran's official site says they achieved the massive drum sound by putting mics at the top of a nearby elevator shaft. https://www.youtube.com/watch?v=Hw1t7OCESUw
