Vibe Coding For Grownups

With

Gene Kim

13 May 2025

Over the past year, Gene Kim has worked with Steve Yegge—known for his 20 years at Amazon and Google—to explore how vibe coding can boost developer productivity. Steve regularly produces 12,000 lines of high-quality, tested code per day using 3–4 AI agents, spending nearly $80,000 annually on AI tokens. While powerful, AI-assisted coding has risks. Gene and his team have seen AI silently delete tests, generate incomprehensible codebases, and nearly wipe a CNC machine. Still, Gene believes developers shouldn't have to code by hand anymore. Vibe coding allows them to build faster, aim higher, work solo, have more fun, and explore freely. These insights will appear in his upcoming book, Vibe Coding: Building Production-Grade Software With GenAI, Chat, Agents, and Beyond, out later this year.

The Evolution of Vibe Coding

Gene Kim's talk, "Vibe Coding For Grownups," explores the transformative impact of AI-assisted coding on the software development landscape. This concept, dubbed "vibe coding" by Dr. Andrej Karpathy, signifies a shift towards minimal manual typing and maximized AI intervention in coding tasks. Kim draws parallels to historical industry disruptions, likening current innovations to the influence of Toyota on American manufacturing in the 1980s, illustrating the profound nature of this transformation.

Kim's journey began in 1999 at TripR, where he embarked on a quest to understand the mechanisms behind high-performing technology organizations. This exploration led him to the forefront of the DevOps movement, collaborating with prominent figures like Patrick Dubois, Dr. Nicole Forsgren, and Jez Humble. The talk also references Steve Yegge’s pivotal Amazon memo, which underscores the importance of "API-First" thinking in today's automated deployment environments.

Unpacking the FAFO Framework

In his discussion, Kim introduces the FAFO framework, which encapsulates the benefits of vibe coding:

  • Faster: Projects are completed at unprecedented speeds, thanks to AI assistance.

  • Ambitious: Developers can now undertake larger and more complex projects.

  • Fully Independent: Reduced need for team coordination allows individuals to achieve more solo.

  • Fun: Vibe coding injects joy and creativity into development, with Kim stating, “I’ve never had as much fun as I’m having now.”

  • Options: AI expands the range of possible solutions, offering more opportunities to identify optimal paths.

Kim provides personal anecdotes, such as rapidly prototyping complex data pipelines and conducting statistical analyses with limited prior Python experience, all facilitated by AI tools. For his and Yegge’s upcoming book "Vibe Coding," they developed bespoke tools using vibe coding, highlighting the process with impressive statistics like burning through 70 million tokens in 30 days.

Navigating the Challenges of AI-Driven Development

Despite its benefits, vibe coding is not without its pitfalls. AI-generated code can lead to tightly coupled, incomprehensible architectures, which Kim refers to as “eldritch horrors.” He emphasizes the importance of modularity and rapid feedback loops to prevent turning “nicely modular code into a big ball of mud.” Fast, granular feedback is crucial to maintaining code quality and system coherence.

Gene Kim draws from the State of DevOps research to discuss how high performers achieve superior outcomes through small, frequent deployments and integrated security. However, he notes a paradoxical finding: increased AI usage sometimes correlates with reduced throughput and stability, a phenomenon his team is investigating. Kim hypothesizes that architectural soundness and feedback speed are key differentiators.

Practical Strategies for Maximizing Vibe Coding

Kim shares practical strategies to maximize the benefits of vibe coding while mitigating its risks. He advocates for test-driven development, modular design, and careful task decomposition. These practices are supported by insights from industry veterans like Eric Meyer, Bruno Passos (Booking.com), and Fernando Coronago (Adidas), who report substantial productivity and happiness gains when AI is used judiciously alongside strong architectural practices.

In conclusion, Gene Kim celebrates the unprecedented opportunities vibe coding presents, expressing eagerness to learn from others' experiences and inviting practitioners to share their stories. He hints at more insights to come in the forthcoming "Vibe Coding" book and future conferences, encouraging developers with the rallying cry: “What a time to be alive—let’s build the future, together.”
