"Using coding agents well is taking every inch of my 25 years of experience as a software engineer." Simon Willison (@simonw) is one of the most prolific independent software engineers and most trusted voices on how AI is changing the craft of building software. He co-created Django, coined the term "prompt injection," and popularized the terms "agentic engineering" and "AI slop." In our in-depth conversation, we discuss: 🔸 Why November 2025 was an inflection point 🔸 The "dark factory" pattern 🔸 Why mid-career engineers (not juniors) are the most at risk right now 🔸 Three agentic engineering patterns he uses daily: red/green TDD, thin templates, hoarding 🔸 Why he writes 95% of his code from his phone while walking the dog 🔸 Why he thinks we're headed for an AI Challenger disaster 🔸 How a pelican riding a bicycle became the unofficial benchmark for AI model quality Listen now 👇 youtu.be/wc8FBhQtdsA





The Buy vs Build dilemma is no more. Always start by building.

President of @Replit Michele Catasta (@pirroh) explains why the decreasing cost of building tools has lead to several key shifts across start-ups: "Before you had to make the choice of shelling out tens of thousands of dollars, spending several months creating the first version of an internal tool - you'd rather go out and buy a SaaS". "The cost of creating it and putting in front of your employees and finding out if it helps or not has become extremely low." "So now that order has completely flipped and I think this trend can't really be stopped". "We're just at the beginning, these are the early innings of the game".
