#3 About vibe coding

November 28, 2025 · 01:10:52 · Krisztian Fischer & Toby Sears

Show Notes

In this episode, Toby and Krisztian explore vibe coding — building software using AI tools and natural language rather than writing code directly. Krisztian shares hands-on experiments with Replit and Cursor, the hosts discuss the impressive speed of prototyping versus the frustration when things go wrong, and they dig into the hidden security risks of putting powerful development tools in the hands of non-technical users. The conversation also covers AI-assisted cyberattacks, supply chain vulnerabilities, and what the explosion of AI-generated apps means for the software industry.
