Perspective on AI Agents
After 52 years of programming, Beck has embraced AI agent workflows for ambitious personal projects, including building a Smalltalk server. DHH describes Beck’s approach as a model of sustainable AI adoption: working intensely with agents on ambitious projects, then stepping away to enjoy nature and maintain balance. Beck demonstrates that the agent revolution isn’t just for young developers — it’s especially powerful for experienced practitioners who know what they want to build.
