03 / Two Questions
Two Different Questions That Sound The Same

"Ethics of AI" is not the same as "Ethical AI."

Ethics of AI · principles

What rules should govern these systems?

An outside-in question. Regulations, declarations, constitutions, bills of rights. Asks who has standing, who decides, who is harmed, who is accountable.

Ethical AI · behavior

How should this model act, right now?

An inside-out question. Refusal, safety, fairness, alignment. Asks how the system itself behaves under pressure — what it says yes to and what it says no to.

Most of today's panel lives in the first column. Most of what AI companies talk about lives in the second. The gap between them is where most of the disagreement actually sits — Siau & Wang (2020).

04 / History
Where The Field Began

Dartmouth, summer 1956. Seventy years of waiting for the room we're in.

A small group of scientists gathered at Dartmouth for a Summer Research Project on Artificial Intelligence. They coined the term. The field begins.

For the next seventy years AI lived mainly in science fiction and in a small community of industry researchers and academics quietly building the digital infrastructure the modern systems would need.

What changed in the last three years isn't the idea — it's the infrastructure. The questions waiting from 1956 arrived all at once.

APH&AI · Ethics Panel
05 / Inherited Frames
Two Frames We Inherited From The Twentieth Century

Useful, partial, and still load-bearing in 2026.

1942 · Asimov · "Do No Harm"

The Three Laws of Robotics.

Asimov's framing — robots must not harm humans, must obey, must protect themselves — is fiction, not law. But the deep instinct it encodes (prevent harm to humans, by design) shows up in every modern AI safety practice: refusal training, red-teaming, evals.

The point isn't to apply the laws. The point is that the field still asks Asimov's question first.

2022 · Brynjolfsson · The Turing Trap

Human-like ≠ human-empowering.

The Turing Trap warns that pushing AI toward imitation of humans tends to replace workers rather than augment them — driving wages down and concentrating economic and political power.

"More human-like" is not a self-evidently good design goal. The frame matters.

Part 01 · Two Grammars
Part 01

Who writes
the rules?

Corporate AI constitutions and public AI bills of rights are doing very different work. Alondra Nelson argues one of them is structurally insufficient.

APH&AI · Ethics Panel
07 / Two Documents
Two Foundational Documents · Two Sources Of Legitimacy

A corporate constitution and a public bill of rights are not the same kind of object.

Type 01 · Corporate AI Constitution

Internal training and alignment spec.

The model developer's vision of how its own model should behave. Canonical example: a frontier-lab "constitution" document used in training.

  • Written and revised by company fiat
  • Not negotiated with affected publics
  • Newer revisions can quietly remove references to international human-rights frameworks
  • Legitimacy comes from the company's own authority
Type 02 · Public AI Bill Of Rights

Democratic rights claim against algorithmic power.

Developed through public process. Canonical example: the White House OSTP Blueprint for an AI Bill of Rights, October 2022.

  • Declares principles publics can extend to new institutions and new harms
  • Five principles: safety, discrimination protections, data privacy, notice/explanation, human alternatives
  • Force comes from democratic legitimacy and the surrounding legal infrastructure
  • Structurally closer to a Declaration than to a Bill — declares, but does not enforce

APH&AI · Ethics Panel
08 / Civic Grammar
Nelson's Argument

A shared vocabulary for rights claims is moving across actors who agree on almost nothing else.

A civic grammar — non-discrimination, transparency, data privacy, notice, human alternatives — that has been traveling across jurisdictions, partisan lines, and institutional contexts.

Alondra Nelson · Science · 2026
The pattern

An American tradition — Patients', Consumer, Tenants', Workers', Taxpayers' Bills of Rights. The AI Bill of Rights template is spreading the same way.

The mechanism

Institutional diffusion among weakly related actors (Strang & Meyer). Conceptual, not relational. Connecticut Democrats, Oklahoma Republicans, and a national student-advocacy network can adopt the same vocabulary because each, separately, met the same algorithmic harm.

APH&AI · Ethics Panel
09 / Marshall
T. H. Marshall · Citizenship And Social Class · 1950

Rights expand in waves. AI rights map onto Marshall's social tier.

18th c.
Civil rightsWave 01
Liberty of person, speech, faith, property. Individual freedoms against arbitrary state power.
19th c.
Political rightsWave 02
The franchise. Participation in collective political authority. Universal suffrage as the long-running expansion.
20th c.
Social rightsWave 03
Economic security and the conditions of participation. Entitlements against harms of industrial capitalism that civil-liberties frameworks could not address.
21st c. ?
AI rightsNelson's argument
Entitlements against systems "that increasingly govern access to employment, credit, healthcare, housing, and education." Collective, diffuse, opaque harms. A social-citizenship response to algorithmic power.

"Rights are never fully delivered at the moment of declaration. They are successively rearticulated by publics who attempt to hold institutions to commitments those institutions have not yet honored." — Nelson, paraphrasing Marshall.

APH&AI · Ethics Panel
10 / Limits
What Civic Grammar Cannot Do On Its Own

Three failure modes Nelson is clear-eyed about.

01
Accommodation can mimic transformation.
A vocabulary that moves easily across partisan lines may have been "drained of the political content that gives rights claims their force." Crossing the aisle is not the same as biting.
02
Rights individualize structural problems.
Frameworks built around individual claims often fail to address the collective and systemic nature of algorithmic harms. A model isn't biased against you — it's biased against a class you sit inside.
03
Declaration is not delivery.
"Declarations of entitlement and their substantive delivery can remain decades apart, separated by the organized power of those who benefit from the status quo."
Nelson's question
Will democratic institutions take this civic grammar seriously before the AI companies finish writing their own constitutions for us all?
APH&AI · Ethics Panel
11 / Three Imperatives
Field Theory · Daedalus · Winter/Spring 2026

Three things AI is, at the same time, for any field that studies it.

01 · QUESTION

AI as social-science question.

Renewed attention to social theories of how technology, human experience, and social order are entangled. Weber on rationalization, Du Bois on technology and inequality, contemporary work on algorithmic governance.

02 · OBJECT

AI as object of inquiry.

The systems themselves merit study as social, political, and economic artifacts — not just engineering products. Training corpora, labor relations, ideological commitments, institutional effects.

03 · TOOL

AI as method / tool.

AI capabilities may transform — or upend — the practice of social investigation itself: large-scale text analysis, multimodal pattern detection, conversational interviewing at scale. Worth critical scrutiny, not uncritical adoption.

Diagnostic use: when you read a piece of AI-ethics scholarship, ask which imperative it engages. That often clarifies what kind of argument is being made — and what kind of counter-argument would land.

Part 02 · A Moral Response
Part 02

Magnifica
Humanitas.

May 2026. Pope Leo XIV's first encyclical places AI alongside the industrial revolution — and arrives at the same conclusion as Nelson from a very different starting point.

Addressed Catholics & "every person of goodwill"
The date is the argument

May 15, 2026 is the 135th anniversary of Pope Leo XIII's Rerum Novarum (1891) — the foundational encyclical of modern Catholic social teaching, written for the dignity of workers under the 19th-century industrial revolution. Leo XIV places AI explicitly alongside that disruption.

A break with tradition

Pope Leo personally presented the encyclical at the Vatican, alongside a co-founder of a frontier AI lab. The first time a pontiff has presented an encyclical himself rather than delegating to cardinals — a signal that the conversation is dialogic, not purely adversarial.

APH&AI · Ethics Panel
14 / Core Teachings
The Center Of The Encyclical

The dignity of the human person is affirmed as infinite. Two ideologies are named.

Critique 01 · Transhumanism

Engineering away human finitude.

The project of using technology to overcome biological limits — aging, mortality, embodiment. Leo XIV rejects the framing of human finitude as a problem to be solved.

Critique 02 · Posthumanism

Blurring the human/machine line.

The philosophical position that humans and machines are continuous, or that human distinctiveness is illusory. Named as an active "anti-human vision" embedded in contemporary AI development — not merely a speculative stance.

Evaluation frame
Dignity of the person · Common good · Justice. The three principles against which any AI deployment is measured.
Coverage
Education · economy · unemployment · work · human trafficking · war. The full social-impact terrain Catholic social teaching has historically addressed.
APH&AI · Ethics Panel
15 / Calls To Action
From Doctrine To Demand

Two operational claims — and one rhetorical move that does work outside the Church.

"
Disarm AI.

Withdraw AI from military applications and from purely economic interests. Direct it toward the common good. The framing is deliberately stark.

§
Regulate it.

Stricter state and international regulation of AI companies. Not industry self-governance. The encyclical does not treat the two as substitutes.

Address everyone.

"Every person of goodwill" — the same rhetorical move Laudato Si' (2015, on climate) and Antiqua et Nova (2025, on AI) used to seek ethical common ground beyond doctrinal lines.

Convergence
Pope Leo and Alondra Nelson arrive at the same conclusion from very different starting points: corporate self-governance is structurally insufficient as a source of legitimacy.

Part 04

The bill
nobody
itemized.

A frontier model has a body. Silicon, electricity, water, copper, land. What an honest accounting of the environmental cost looks like — and where it lands.

APH&AI · Ethics Panel
19 / Where The Cost Lands
Four Inputs · One System

Every prompt sits on a stack of physical inputs. Worth naming them out loud.

Electricity.

Training a frontier model and serving its inference both draw megawatts continuously. Datacenter demand is now a material driver of grid planning in several U.S. regions.

💧
Water.

Evaporative cooling consumes potable or industrial water — sited disproportionately in arid regions. The Southwest is a relevant case in this room.

Embodied carbon.

Accelerator manufacturing, server build, building shell, fiber, copper. The carbon cost is paid before the first prompt — and is rarely on the accounting.

🏗
Siting & land.

Hyperscale datacenter buildout reshapes local economies, tax bases, transmission corridors, and noise envelopes. The externalities are not evenly distributed.

Frame: AI's environmental cost is not one number. It is at least four numbers, on at least three timescales (training, inference, buildout).

APH&AI · Ethics Panel
20 / Marginal Cost
A Per-Call Heuristic

Two questions worth asking before every agentic loop.

Q1 · Right-size the model

Does this task actually need the frontier?

Tiny / local
Small hosted
Mid
Frontier

Per-call energy and embodied compute scale with model size. Most tasks fit inside a smaller model — defaulting to the frontier is a habit, not a requirement. (Figure is illustrative, not measured.)

Q2 · Right-size the loop

Does this agent need to retry forty times?

One-shot
+ retries
+ tool calls
Speculative agent

Agentic loops fire speculative calls, retries, and tool calls behind one user action. Cumulative compute, not the visible turn count, is the cost. Cache. Cap retries. Watch the loop.

APH&AI · Ethics Panel
21 / Bridge
Bridge · The Two Halves Are The Same Conversation

Environmental impact is an ethics question. Same publics. Same diffuse harms.

Collective, diffuse, opaque harms that older rights frameworks address only partially.

Nelson · on algorithmic harms — and equally on environmental ones
Same structural pattern

Datacenter siting, grid load, and water draw produce harms that are collective, diffuse, and opaque — the same shape as algorithmic harm. Marshall's social-rights tier is the same conceptual address.

Same convergence

Laudato Si' (2015, on care for creation) and Magnifica Humanitas (2026, on AI) share a single underlying claim: the environment and the economy and the technology are one moral question.

Over to
the panel.

Six prompts. The framing above is shared substrate — disagreement with it is fair game.

APH&AI · Ethics Panel
23 / Questions
Six Prompts For The Panel

Pick the one you most want to argue with first.

Q1 · Legitimacy
If corporate AI constitutions are structurally insufficient, what is the minimum public mechanism that is sufficient?

Not principles. Mechanism.

Q2 · Civic grammar
Is the convergence across partisan lines a sign of strength — or evidence the vocabulary has been drained of force?

Nelson asks both. Pick one to defend.

Q3 · Magnifica Humanitas
Does the theological vocabulary (infinite dignity, transhumanism, posthumanism) help or hinder public deliberation about AI?

You can dislike the framing and still answer.

Q4 · Public health
What algorithmic harm in public health practice today would most benefit from a Marshall-style social-rights response?

Be specific. Name a system.

Q5 · Footprint
Is "use a smaller model when you can" an adequate environmental ethic — or is it a personal-virtue dodge?

Compare to "use less plastic."

Q6 · Trade-off
When does a documented public-health benefit of an AI tool outweigh its documented environmental cost — and who gets to decide?

The hardest question. Save it for last.

End · Thank You
Three days. One conversation that doesn't end here.

Keep
arguing.

The civic grammar gets traction because publics use it. The footprint shrinks because engineers and researchers refuse the default. Both are unfinished work — and both belong to the room that just spent three days in it.
