Matt Van Horn is the author of the X Article "WTF Is a Loop? Peter Steinberger vs. Boris Cherny," which explains the 2026 AI-coding discourse around agent-loops. In the article, he frames loops as a shift from prompting agents manually toward writing durable systems that prompt, evaluate, schedule, and supervise agents.source: matt-van-horn-wtf-is-a-loop-2026.md
His synthesis is skeptical of both pure hype and pure dismissal: loops reuse old infrastructure such as cron, but add model-driven decisions, feedback, budgets, and orchestration. He argues that the durable unit inside a useful loop is a reusable skill, connecting his view to skillification and harness-engineering.source: matt-van-horn-wtf-is-a-loop-2026.md
