Agentic systems: from answering to acting
The meaningful shift is not better prose, it is systems that call tools. An agent chooses an action, executes it against a real system, checks the result and continues until the task is done or it needs a person. That moves AI from a drafting aid to something that completes work.
What it means in practice
- Permissions, logging and rollback stop being nice-to-haves and become part of the build
- The interesting failure mode changes from a wrong sentence to a wrong action in a live system
- Value is measured in tasks completed rather than words produced
