Pattern: The Vibe-Coding / Agentic-Engineering Line Is Blurring Into One Continuum

Simon Willison·medium signal

Practitioners (Simon Willison among them) note the boundary between 'vibe coding' (prompt-and-accept) and 'agentic engineering' (spec + tests + explicit verification loop) is collapsing as tools add guardrails to both modes. The practical takeaway is to choose mode per task: vibe to raise the floor on throwaway or exploratory work, agentic engineering to raise the ceiling on production code where a wrong outcome is unacceptable.
