Jeff Hwang and Seymour Duncker

A new podcast about the world of generative AI, including ChatGPT, Large Language Models (LLMs), DALL-E, Stable Diffusion, and more

  1. EPISODE 1

    Episode 1 - What is ChatGPT?

    Jeff and Seymour kick off the podcast with an exploration of ChatGPT. What is it and how might it impact our careers and lives? They use ChatGPT and large language models (LLMs) as an entry point to the larger topic of generative AI. Questions and comments? Talk to us.

    Episode 2 - Who Opened The Floodgates?

    Jeff and Seymour discuss the unexpected impact of ChatGPT and how Bing Chat may not be ready for prime time. Did OpenAI unintentionally open Pandora's Box because they were worried someone else would beat them to it? Plus some reassurances that Sydney is definitely not sentient or emotional. Kevin Roose's article in The New York Times and transcript of his long chat session with Bing / Sydney. Podcast episode detailing the behind the scenes at OpenAI in the weeks leading up to the launch of ChatGPT in November, 2022 as discussed by Roose and Casey Newton on their show Hard Fork.

    Episode 3 - Elevators Up, Stairways Down

    Jeff and Seymour use stories and analogies to explain the two main approaches to AI: Bottom-Up and Top-Down. The recent wave of AI success is mostly based on the bottom up  path which includes machine learning, neural networks, and deep learning.

  4. EPISODE 4

    Episode 4 - Typeface and Cezanne's Card Players

    Jeff and Seymour discuss the launch of a new marketing company using generative AI called Typeface. This leads to a conversation about copyright consent, compensation, and credit. We discuss how the history of photography, Napster, and Paul Cézanne's The Card Players might help us understand the future of image generators like DALL-E, Midjourney, and Stable Diffusion. Questions and comments? Talk to us.

    Episode 5 - Lightbulbs or Lava Lamps? DALL-E in The New Yorker

    Jeff and Seymour dig further into image generators like Midjourney, DALL-E, and Stable Diffusion. What is the role of the visual artist as generative AI tools continue to evolve? How might it replicate the relationship between a great writer and a trusted magazine editor?

  6. EPISODE 6

    Episode 6 - Where Will Generative AI Startups Win and Lose?

    Jeff and Seymour start with another major week of news, including GPT-4, Microsoft and Google adding generative AI to their office suites, and LLaMA breaking out into the wild and onto Raspbery Pi and smartphones. Simon Willison's 3-day history of LLaMA developments this past weekend. Potentially bigger news than the dramatic collapse of Silicon Valley Bank. Two relevant articles from Elad Gil: Startups vs Incumbents and Why weren't there any big startup winners from the last 10 years of deep learning? Coca-Cola commercial set in an art museum using Stable Diffusion PCs disrupting mainframes in the 1980s in the context of Clay Christiensen's Innovator's Dilemma and theory of disruptive vs sustaining innovation Runway ML applying Stable Diffusion to generative AI for video  Questions and feedback? Let us know.

  7. EPISODE 7

    Episode 7 - Bigger than Prometheus?

    Jeff and Seymour debate the significance of the generative AI revolution relative to the invention of the WIMP interface, the web, and even the Industrial and Agricultural Revolutions.  Prometheus refers to the humans learning how to control fire; is gen AI bigger than that?! Articles referenced: Bill Gates "The Age of AI Has Begun"  Thomas Friedman "Our New Promethean Moment" (NY Times) Rodney Brooks on GPT and related LLM technology  Send questions/comments to stepfunctionpod@gmail.com and find us on the web at www.stepfunction.org

  8. EPISODE 8

    Episode 8 - Moore's Law, Exponential Improvements, AI Chips, Emergent Behavior

    The news that Gordon Moore passed away broke last Friday just as we were recording the previous episode. Today, Jeff and Seymour discuss Moore's legacy, the past and future of Moore's Law, and how advancements in microchips have been the foundation of deep learning for more than a decade. Links: NY Times obituary for Gordon Moore and a remembrance by Walden Kirsch at Intel. Apple's latest iPhone has an A16 Bionic system-on-a-chip with 16 billion transistors, compared to 1993's then ground-breaking Intel Pentium which had 3 million transistors. Articles on Moore's Law and Dennard Scaling Excellent piece by The Computer History Museum in Mountain View, CA. 2018 piece by Micron on Moore's Law and Dennard Scaling (aka MOSFET scaling). 2007 piece in IEEE on 30 years of Dennard/MOSFET scaling (PDF). Types of chips AI Accelerators and Deep Learning Processors (DLP). CPUs, FPGAs, and ASICs. Google's Tensor Processing Units (TPUs). Accleration of AI progress above Moore's Law Seymour refers to the chart in this 2021 IEEE Spectrum article. 2022 article in Discover magazine by the Physics arXiv Blog.
