- Quoting Charity Majors
Quoting Charity Majors — simonwillison.net · 20h ago · 💡 Opinion / Essays
The article highlights Charity Majors’ observation that the economics of code production were fundamentally inverted in 2025 due to AI. Code generation, once a difficult, time-consuming, and expensive process, became effectively free and instantaneous. This shift transformed lines of code from being treasured and carefully curated assets into disposable and regenerable commodities. The core takeaway is that AI has profoundly altered the value proposition and required engineering discipline for software development. 💡 Why read it: It offers a concise, impactful perspective on how AI is reshaping the fundamental economics and perceived value of software code. 🏷️ AI economics, code production, engineering discipline, Charity Majors
- You Got Faster. Your Company Didn’t.
You Got Faster. Your Company Didn’t. — terriblesoftware.org · 20h ago · 💡 Opinion / Essays
This article addresses the counterintuitive phenomenon where individual developer speed increases with AI tools, but overall company productivity remains stagnant. It argues that AI makes individual developers faster by merely outsourcing the ‘slow part’ of the process to other team members or later stages. Consequently, bottlenecks are not eliminated but simply shifted within the organizational workflow. The main conclusion is that true company-wide productivity gains from AI require addressing systemic bottlenecks, not just individual speed improvements. 💡 Why read it: It critically examines the often-overlooked systemic impact of AI on organizational productivity, beyond individual developer speed. 🏷️ AI, Productivity, Software development, Team dynamics —
