Beyond Chatbots: How Agentic AI is Redefining Organizational Structures from Heroism to Stewardship

The software industry stands at a inflection point. For decades, engineering organizations have operated on a model of human heroism: skilled engineers diagnose production fires, manually patch critical systems, and carry institutional knowledge that no ticket tracker can capture. That model is now being stress-tested at scale—and a growing number of engineering leaders are asking whether heroism is a feature or a bug.

At Stripe, the question yielded an unexpected answer. The company’s internal agentic infrastructure—informally called the “Minions” system—now generates and merges approximately 1,300 pull requests per week with no direct human coding. The system’s architecture offers a rare, detailed look at how autonomous AI agents can operate within a production engineering environment, and more importantly, what their existence means for how organizations are structured.

The Rise of World Models: Bridging the Gap Between Large Language Models and Physical Reality

Susiloharjo

The Rise of World Models: Bridging the Gap Between Large Language Models and Physical Reality Artificial intelligence has achieved remarkable feats in natural language processing, code generation, and creative domains. Yet the most sophisticated language models still stumble when asked to predict what happens if a glass falls off a table, or to plan a … Read more

Hisab vs Rukyat: The Astronomical Algorithms and Mathematical Models Defining Idul Fitri 1447 H

Astronomical telescope and mathematical models of lunar crescent sighting

Hisab vs Rukyat: The Astronomical Algorithms and Mathematical Models Defining Idul Fitri 1447 H As the Islamic lunar calendar approaches its culmination point, Indonesia faces a familiar astronomical divergence. The determination of 1 Syawal 1447 H—marking Eid al-Fitr 2026—relies on two fundamentally different methodological approaches: Hisab (astronomical calculation) and Rukyat (empirical lunar crescent observation). This … Read more
