Every wave of automation reaches a point where the limiting factor shifts from what the machine can do to how much human attention it consumes. Mainframes reached it with operators; data centers with administrators; the cloud with the engineers who once managed fleets of servers by hand. Each time, the breakthrough came from moving the knowledge of what to do next out of a person's head and into a system that could carry it.
AI agents have now reached that point. An agent can competently write code, reconcile an invoice, or triage a support ticket. Yet, the work around the task still falls to a person: deciding the next step, remembering what was agreed an hour ago, insisting on a review, sending the findings back for a fix. Anyone who has worked alongside a coding agent all day knows the pattern. The output arrives quickly, and the human spends the day steering it.

That supervision cost rarely appears in a business case, and it quietly decides whether agentic AI scales. Techaisle data shows 59% of midmarket firms now prioritize agentic AI in their budgets, and AI-driven algorithmic decision-making has doubled to 20%. Leading-edge midmarket firms running custom agentic ecosystems have reached 144 agents for every employee, and small businesses 59. At that density, an agent that needs a human prompt every few minutes stops being leverage, and the human becomes the bottleneck the agents were meant to remove. Kiro workflows, introduced by AWS on September 30, are one of the first serious attempts to engineer that supervision cost out of the product. They are worth studying for what they reveal about where agentic AI is heading.
