AI-First Development Creates Zero Bus Factor Risk
Estimated read time: 5 min
The article explores how AI-first development practices create a dangerous "Bus Factor of zero" where no human understands the codebase. This shift from traditional knowledge preservation to "vibe coding" with LLMs poses significant risks for maintenance, debugging, and security in software projects.
Building AI Products in the Probabilistic Era
Estimated read time: 15 min
Software development is undergoing a fundamental shift from deterministic to probabilistic systems. Unlike traditional apps with predictable inputs/outputs, AI products operate with infinite possibilities and stochastic results. This requires developers to adopt empirical approaches over engineering certainty, manage uncertainty rather than eliminate it, and build sophisticated data systems to track user trajectories through emergent AI capabilities.
