The Subject Who Signs

AI can generate corporate documents, analyses, and recommendations at unprecedented speed. But responsibility does not migrate with generation. This essay examines why accountability remains irreducibly human, how decision boundaries function as institutional facts, and why organizations must deliberately design responsibility— not merely govern models— in an age of machine-generated decisions.

Why AI Can Generate Decisions—but Cannot Own Them

Responsibility in an Age of Machine-Generated Decisions

There is a quiet revolution underway in how corporations produce their most consequential documents. Quarterly earnings reports, regulatory filings, risk disclosures, board memoranda—artifacts that once required teams of analysts working through weekends—can now be drafted in minutes. Large language models trained on decades of financial data can generate text that is not merely plausible but often indistinguishable from what human professionals would produce. The prose is clean. The formatting is correct. The numbers reconcile.

And yet something essential remains unchanged. When the Chief Financial Officer signs an annual report, when a board chair attests to the accuracy of securities disclosures, when an auditor issues an opinion on financial statements—the weight of that signature has not diminished by a single gram. The document may have been generated by a machine, but the responsibility for its contents remains irreducibly human.

This observation is not a warning about AI. It is a statement about institutional reality—and an invitation to examine what that reality now demands of organizational design.


The Generation-Responsibility Gap

Consider what happens when a publicly traded company files its annual report with securities regulators. The document contains forward-looking statements, revenue recognition judgments, risk factor disclosures, and assertions about internal controls. These are not merely descriptions of fact; they are formal commitments that carry legal force. Officers who sign these documents certify, under penalty of law, that they have reviewed the contents and that the information is accurate to the best of their knowledge.

Now consider the production process. An AI system can gather historical financial data, compare it against peer disclosures, apply regulatory templates, flag inconsistencies, and generate draft language that conforms to accounting standards. It can do this faster and more consistently than any human team. But when the SEC later discovers that revenue was improperly recognized, or that a material risk was omitted, or that the company’s internal controls were in fact inadequate—the investigation does not turn to the AI system.

It cannot. The AI is not a legal person. It cannot be deposed, fined, imprisoned, or barred from serving as an officer. It cannot be held in contempt of court. It has no assets to seize, no reputation to destroy, no liberty to forfeit. The entire apparatus of accountability—civil, regulatory, and criminal—presupposes a subject capable of bearing consequences. AI, regardless of its sophistication, is not that subject.

This is not a limitation that future technical progress will resolve. It is a structural feature of how responsibility functions in institutional contexts. Responsibility requires not just causation but attribution to an entity that can answer for outcomes. The corporation, the officer, the auditor—these are not merely nodes in a process flow. They are accountable subjects in a system that demands someone stand behind every consequential claim.


Why Governance Discourse Stops Too Early

The dominant conversations about AI in corporate and regulatory settings tend to focus on a familiar set of concerns: model explainability, algorithmic bias, human-in-the-loop oversight, and model risk management. These are legitimate issues. A credit decision made by an opaque algorithm raises genuine questions about fairness. A medical diagnosis generated by a neural network demands some form of interpretability. The model risk frameworks developed by financial regulators represent serious attempts to ensure that AI systems operate within acceptable parameters.

But these frameworks, important as they are, address a different layer of the problem. They ask: How do we ensure the AI system behaves appropriately? They do not ask: Who bears formal responsibility when a decision goes wrong?

The distinction matters enormously. A human-in-the-loop requirement, for instance, might ensure that a person reviews an AI-generated recommendation before it takes effect. But “review” is not the same as “responsibility.” If the reviewer is presented with an AI output that appears reasonable, lacks the time or expertise to interrogate it deeply, and approves it as a matter of routine—who is truly accountable when the decision proves catastrophic? The human was in the loop, but were they the actual decision-maker? Or were they a procedural checkpoint in a process whose real locus of judgment had already shifted elsewhere?

Model risk management frameworks typically require documentation, validation, and ongoing monitoring of AI systems. These are prudent controls. But they manage process risk, not responsibility assignment. The question of who signs, who attests, who answers to regulators and shareholders—this remains downstream of model governance, and often unexamined.

The most sophisticated AI governance regimes in the world can coexist with a profound ambiguity about accountability. And that ambiguity is not a technical problem awaiting a technical solution. It is an organizational design problem that requires explicit architectural choices.


From Boundaries to Design

There is a concept that clarifies what is at stake: the decision boundary. A decision boundary is a formal demarcation point where authority is exercised and consequences attach. The CFO’s signature on a quarterly filing is a decision boundary. The board’s approval of a major transaction is a decision boundary. The auditor’s opinion letter is a decision boundary. These are the moments at which organizational process crystallizes into institutional commitment—where output becomes attestation and attestation becomes liability.

Decision boundaries already exist throughout corporate law, securities regulation, fiduciary duty, and professional licensing regimes. The signature on a document is not a ceremonial flourish; it is a legal act that binds the signer to the contents. The attestation clause in an audit report is not boilerplate; it is a warranty backed by malpractice exposure and regulatory sanction.

But here is the critical point: decision boundaries do not emerge naturally. They are artifacts of prior organizational choices. Someone, at some point, determined that this role would carry signature authority, that this committee would hold approval rights, that this function would bear attestation responsibility. These determinations constitute what might be called Decision Design—the intentional architecture of who holds decision authority, under what conditions, and with what accountability for outcomes.

Decision Design is not policy. It is not ethics. It is organizational architecture: the deliberate structuring of responsibility within an institution so that consequential judgments have identifiable owners. In stable environments, this architecture often operates invisibly, embedded in role definitions, governance charters, and regulatory requirements that predate any particular decision. But AI destabilizes this invisibility. When machines can generate the substantive content of decisions, the question of who owns those decisions—who stands behind them institutionally—becomes suddenly and urgently visible.


The Risk of Decisional Drift

What AI does is generate the content that flows toward decision boundaries. It can accelerate the production of drafts, analyses, and recommendations. It can surface patterns that humans might miss and flag inconsistencies that deserve scrutiny. But it cannot move the boundary itself. The signature line remains where it was. The attesting officer remains who they were.

The danger is not that AI will seize responsibility. It cannot. The danger is that responsibility will become diffuse—spread so thin across processes, systems, and perfunctory approvals that no one truly owns the decision anymore. The organizational form appears intact: documents are signed, boxes are checked, approvals are logged. But the substance of accountability—the genuine assumption of personal or corporate risk for the contents of a decision—has quietly evaporated.

This is decisional drift: the gradual migration of actual judgment away from formal responsibility. The decision boundary still exists on paper, but it no longer reflects where the real determination occurs. The CFO signs, but the analysis was generated. The board approves, but the recommendation was algorithmic. The auditor attests, but the testing was automated. In each case, the institutional subject remains formally accountable for a decision whose substance was shaped elsewhere.

Decisional drift is not caused by AI. It can occur whenever organizational complexity outpaces accountability design. But AI accelerates it dramatically, because AI makes it easy to generate sophisticated outputs that look like decisions without requiring anyone to genuinely make them.


Designing for Responsibility

This is why the most important question for organizations deploying AI is not how capable is the system? or even how do we govern the model? The most important question is: Who will formally bear responsibility for decisions that AI helps produce?

The answer cannot be “the AI team” or “the technology function” or “the vendor.” These may be appropriate targets for process accountability—ensuring the system works as specified—but they are not the right locus for outcome accountability when a decision causes harm.

Nor can the answer be a vague appeal to collective responsibility. When everyone is accountable, no one is. The diffusion of responsibility across committees, workflows, and automated systems is precisely the failure mode that well-designed institutions are meant to prevent.

What organizations need is explicit Decision Design. This means identifying, for each consequential AI-assisted process, the specific human or governance body that will own the final decision. It means ensuring that this party has genuine authority to override or reject AI outputs—not merely a theoretical veto that is never exercised. It means creating documentation and audit trails that make clear who decided, on what basis, and with what understanding of the AI’s contribution. And it means revisiting existing decision boundaries to ensure they still reflect where judgment actually occurs.

None of this is technically exotic. It is organizational architecture of a kind that predates AI by centuries. The corporate seal, the countersignature, the board resolution, the legal opinion—these are all mechanisms for concentrating responsibility at defined points. AI does not render them obsolete. If anything, it makes them more essential, because the ease of machine generation creates new pressures toward decisional drift.


The Signature Remains

We are entering an era in which the production of consequential documents—contracts, disclosures, assessments, recommendations—will increasingly begin with AI. This is not inherently problematic. The generation of text and analysis has always involved tools, from the printing press to the spreadsheet to the word processor. What matters is not the tool but the structure of accountability that surrounds its use.

The signature at the bottom of a securities filing is a small thing, typographically speaking. But it represents something that no AI system can replicate: the assumption of formal responsibility by a subject capable of bearing consequences. It is the point at which generation becomes commitment, where output becomes attestation, where process becomes accountability.

AI can accelerate everything that leads up to that signature. It cannot provide the signature itself. And in that irreducible gap—between what machines can generate and what institutions require someone to stand behind—lies the central design challenge of AI-era organizations.
