The thing about agentic coding is that agents grind problems into dust. Give an agent a problem and a while loop and - long term - it’ll solve that problem even if it means burning a trillion tokens and re-writing down to the silicon. [...] But we want AI agents to solve coding problems quickly and in a way that is maintainable and adaptive and composable (benefiting from improvements elsewhere), and where every addition makes the whole stack better. So at the bottom is really great libraries that encapsulate hard problems, with great interfaces that make the “right” way the easy way for developers building apps with them. Architecture! While I’m vibing (I call it vibing now, not coding and not vibe coding) while I’m vibing, I am looking at lines of code less than ever before, and thinking about architecture more than ever before. — Matt Webb, An appreciation for (technical) architecture Posted 28th March 2026 at 12:04 pm Recent articles Vibe coding SwiftUI apps is a lot of fun - 27th March 2026 Experimenting with Starlette 1.0 with Claude skills - 22nd March 2026 Profiling Hacker News users based on their comments - 21st March 2026 This is a quotation collected by Simon Willison, posted on 28th March 2026. definitions 51 matt-webb 25 ai 1937 generative-ai 1718 llms 1684 ai-assisted-programming 368 vibe-coding 79 coding-agents 186 agentic-engineering 35 Disclosures Colophon © 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 2026
