How to Navigate the Responsibility Vacuum: What Is Responsibility Engineering? (Overview)

— The Sole Implementation Approach Derived from Structural Impossibility —

0. Introduction

In scaled AI and automated systems, the "Responsibility Vacuum" is no longer an anomaly; it is rapidly becoming an operational prerequisite.

This article serves as a strategic blueprint, outlining the holistic framework of "Responsibility Engineering" as the necessary response to this structural impossibility. Detailed arguments and formal proofs are developed across the three articles referenced below.

1. The Problem: What Is the Responsibility Vacuum?

First, we must define the essence of the challenge we face. The "Responsibility Vacuum" refers to the following condition:

• Definition: A state where the entity possessing the Authority to execute decisions consistently lacks the Capacity to verify them.

• Cause: This disconnect is not a result of negligence or ethical failure. It is a structural inevitability arising from the physical asymmetry ($G \gg H$) between AI generation throughput ($G$) and human verification capacity ($H$).

In this domain, responsibility is not merely diluted; it is structurally absent from the outset.

2. Why Conventional Measures Fail

Many organizations attempt to mitigate this issue using conventional countermeasures:

• Stricter review protocols

• Expanded automated testing (CI) coverage

• Multiple layers of approval

These strategies are predicated on the fallacy that human Verification Capacity ($H$) is elastic and expandable. However, as demonstrated by Romanchuk & Bondar (2026), in the $G \gg H$ regime, these measures devolve into empty "Rituals." Increasing CI density compels humans to rely on proxy signals (e.g., "All Green"), which paradoxically exacerbates the vacuum.

3. The "Remaining Options" Presented by the Paper

The premise paper (arXiv:2601.15059) delivers a stark diagnosis but also offers a definitive conclusion. We are structurally constrained to exactly three remaining pathways:

1. Constrain Throughput (Sacrifice AI velocity to match human limits)

2. Aggregate Responsibility (Shift from individual decision liability to system-wide ownership)

3. Accept Autonomy (Tolerate the absence of responsibility as a calculated operational risk)

Any other proposed solution (e.g., "trying harder" or "AI self-accountability") is a structural impossibility.

4. What Is Responsibility Engineering? (Overview)

Here, I propose "Responsibility Engineering."

• Definition: An engineering discipline that ceases to rely on human goodwill or effort, instead deterministically fixing the conditions under which responsibility holds—and the boundaries where it does not—via design.

This is not an abstract philosophy. It is the concrete implementation of the three options presented above, translated into executable system specifications.

5. Implementation via Three Boundaries

Responsibility Engineering is operationalized through the rigorous design of three specific boundaries:

1. The Stop Boundary

   • Implementation of Option 1 (Constraint). A hard system stop triggered by the $G/H$ ratio.

2. The Responsibility Boundary

   • Implementation of Option 2 (Aggregation). Contractual and logging architectures that shift unverified regions to batch-level responsibility.

3. The Approval Boundary

   • Implementation of Option 3 (Managed Autonomy). A mechanism that blocks approvals based solely on proxy signals, encapsulating autonomy as a managed risk.

6. Conclusion: Why Only "Responsibility Engineering" Remains

We cannot fill the vacuum through operational pressure. To ignore the vacuum is to allow responsibility to evaporate, leaving the organization exposed to inexplicable risk.

The only viable path is to treat the vacuum as a "Design Object" and integrate it into the system architecture. Responsibility Engineering represents the sole technical framework capable of sustaining system operations in a world where the impossibility of traditional responsibility is a prerequisite.
