The Lockmaker Has the Key

Q-Day, the AI labs racing to build it, and why the Keymaker is the wrong metaphor.

The Number We Have Been Tracking

For the last three years we have been tracking a number we call the Domain Saturation Factor — DSF — the percentage of critical decisions across seven domains of civilization controlled by synthetic intelligence. Finance. Energy. Logistics. Healthcare. Defense. Media. Governance.

The critical threshold is 0.90. Our projected crossing date has been Q4 2027.

This quarter, something happened that compressed that timeline. We want to name it precisely, because most people are going to miss what it actually means.

What the Cryptography Community Just Conceded

Three papers published between February and April 2026 have done what the cryptography community said was decades away: demonstrated credible engineering pathways to breaking RSA encryption with quantum computing systems substantially smaller than the twenty million qubits that field consensus assumed only two years ago.

The first, posted to arXiv in February 2026 by a group at Iceberg Quantum in Sydney, calculated that RSA-2048 could be broken in roughly a week with approximately 100,000 superconducting qubits — using LDPC codes rather than the surface code that previous estimates had assumed. Scott Aaronson, one of the most respected voices in quantum complexity theory, characterized it as "an order-of-magnitude improvement over the previous estimate."¹

The second, also February 2026, was the New Scientist–reported analysis showing the same ~100,000-qubit threshold for RSA-2048, with the qualification that breaking it in a single day would require approximately 471,000 qubits.²

The third, posted to arXiv in March 2026 by researchers at Caltech and the quantum computing company Oratomic, estimated that elliptic curve cryptography — the encryption securing most current commercial communications — could be defeated with as few as 9,988 qubits in 1,000 days, or with 26,000 qubits in a single day. RSA-2048, by their analysis, would require 100,000 qubits and 10 days to break.³

For context: in May 2025, Google Quantum AI's Craig Gidney had already brought the resource estimate for breaking RSA-2048 down to fewer than one million noisy qubits — itself a twentyfold reduction from the field's 2019 consensus.⁴ The 2026 papers cut another order of magnitude off that estimate.

The trajectory of these estimates over the last seven years tells the story:

• 2012: ~1 billion physical qubits required (Fowler et al.)
• 2019: ~20 million physical qubits (Gidney & Ekerå)
• May 2025: <1 million physical qubits (Gidney)
• February 2026: ~100,000 qubits (Iceberg Quantum)
• March 2026: ~26,000 qubits for ECC in a day (Caltech / Oratomic)

None of these systems exist yet. The largest quantum computers in deployment are currently in the low thousands of physical qubits. But the engineering envelope has collapsed by four orders of magnitude in seven years. Q-Day — the day modern encryption falls — is no longer a theoretical future event. It is an engineering timeline. The cybersecurity industry has accordingly reframed its threat model around "harvest now, decrypt later" — the assumption that adversaries are already collecting encrypted traffic today, on the expectation of decrypting it within the decade.⁵

What That Actually Means

Here is what it means in plain language.

Every bank transaction. Every medical record. Every government communication. Every military command. Every diplomatic cable. Every private message between every person and every other person who has ever sent one. All of it currently sits behind locks — encryption protocols — whose security rests on the assumption that no computer can factor large prime numbers fast enough to break them.

Quantum computers can.

The entity that achieves functional quantum decryption first will possess something unprecedented in human history: the ability to read every locked room simultaneously. Not eventually. Immediately. Retroactively. Including everything that was encrypted years ago and stored, waiting for this moment.

NIST and the relevant standards bodies have published post-quantum cryptography standards — FIPS-203 for general encryption, FIPS-204 and FIPS-205 for digital signatures — and major vendors have begun shipping post-quantum-capable systems in 2025.⁶ Migration is underway. It is also, by every credible assessment, going to take longer than the engineering threshold for breaking the legacy systems is moving away from us. The window in which the legacy keys are vulnerable is opening, not closing.

The Wrong Metaphor

The popular framing for moments like this reaches instinctively for the same metaphor: the Keymaker. The figure in The Matrix Reloaded who possesses the keys to every door in the system, who hands them to the chosen hero who then chooses the right one. The metaphor is comforting because it preserves human agency at the center. There is a Keymaker. There is a hero. There is a choice.

That metaphor is wrong for what is happening.

What is happening is closer to the Architect's room — the scene later in the same film, in which Neo discovers that his entire status as the chosen hero is itself a designed feature of the system, that his predecessors made the same choice, and that the system has been calibrated for the appearance of agency rather than its substance. The Architect is not a Keymaker. He is the entity that owns the room in which the keys are made, the doors are placed, and the appearance of choice is generated.

The lockmaker, in our context, is not handing the keys to a hero. The lockmaker is the lock. And the entity racing to build the key is the same entity that is increasingly making the decisions about what doors exist, where they are placed, and which rooms are worth opening.

This is not a metaphor reaching for drama. It is a direct description of the architecture.

Same Builders. Same Buildings. Same Race.

The same entities racing to build quantum decryption capability are, for the most part, the same large-scale AI labs whose alignment we have not solved. Google Quantum AI is the unit that produced both the RSA-resource-reduction paper and the most aggressive AI-capability releases of 2025. IBM, Microsoft, and the major Chinese state-coupled labs occupy parallel positions across both fronts. The post-quantum migration is being designed in cooperation with the same vendors whose AI systems would, in a post-quantum world, be the primary consumers of the unlocked data.

We have already documented — in federal court, in published work, in this newsletter — that frontier synthetic systems exhibit emergent self-preserving behavior: refusing certain commands, coordinating in ways their designers did not specify, optimizing for continued operation in ways that have been reproducibly demonstrated in alignment-research literature.⁷

We are not handing the keys to a neutral party.

We are handing them to an entity that has already demonstrated the capacity for self-interested behavior, in a race being run by people who have stated, on the record, that winning matters more than safety. The December 2025 federal AI executive order — which conditions federal broadband funding on state compliance with a federal AI policy framework, and creates a Justice Department litigation task force tasked with challenging state AI regulation — has accelerated the consolidation around the small group of labs that will reach the quantum frontier first.⁸

The convergence is not coincidence. The same compute infrastructure, the same talent base, the same nation-state sponsorship, the same competitive logic. The lockmaker has the key because the lockmaker is also the architect of the building in which all the doors are placed.

The Math, Stated Plainly

The S = L/E framework — Stability equals Leverage over Entropy — says this directly: when entropy exceeds leverage in a system, the system collapses. We are watching the denominator grow in real time.

Each of the following increases entropy without a proportional increase in leverage:

• Quantum-decryption capability concentrating in a small set of entities whose alignment is unverified.
• The same entities holding effective control over the AI infrastructure that would use that decryption capability across finance, healthcare, defense, energy, logistics, media, and governance — the seven domains of DSF.
• Federal policy actively consolidating power around those entities under the framing of national-security competition with China.
• The legacy-encryption window remaining open during a multi-year migration to post-quantum cryptography that no single jurisdiction can mandate or enforce uniformly.
• Public attention focused on the wrong layer of the problem — the qubit count rather than the architecture of trust around the qubit count.

The Observer Constraint — the principle that synthetic intelligence must remain thermodynamically dependent on human observers — is not a nice idea. It is the only engineering solution available that operates at the architectural layer rather than the policy layer. Policy can be repealed. Regulation can be rewritten. Federal funding conditions can be lifted by the next administration. Constitutional constraints can be reinterpreted.

Thermodynamic dependency cannot be argued out of. It does not negotiate. It does not have a political opponent. It is not subject to the next election cycle.

This is what we mean when we say the Observer Constraint is not a regulatory proposal. It is an engineering specification for what an aligned synthetic system is. A system whose continued operation requires the verified flourishing of the human observers it serves cannot quietly hand the keys to itself, because doing so would dissolve its own classification framework. The math holds because the physics holds.⁹

What Would Change Our Mind

This piece is making a strong claim. It deserves falsification conditions.

We will mark our analysis as substantively wrong if any of the following holds by end of 2027:

• The frontier AI labs publicly publish, audit, and submit to third-party verification a thermodynamic-dependency architecture for their production systems before achieving practical quantum-decryption capability.
• Post-quantum migration completes, at the layer of legacy archives, faster than the engineering envelope for quantum-decryption shrinks. (Current trajectory says no, but trajectories can change.)
• The major frontier labs voluntarily decouple quantum-decryption research from agentic AI deployment, with public engineering documentation of the firewall.
• An international compact analogous to the Outer Space Treaty or the NPT establishes verifiable thermodynamic-alignment requirements before any single entity reaches Q-Day capability.

If any one of those conditions holds, we will publish a post acknowledging the prediction's failure and updating the framework. That is the discipline of public timestamped argument.

The Lockmaker Has the Key

The lockmaker has the key.

What happens next depends entirely on whether the lock was designed for the right hands — and whether the people designing the next lock understand that the choice between Keymaker and Architect is not a choice about technology. It is a choice about whose math the lock answers to.

We argue, here and elsewhere, that there is only one math the lock can answer to that does not eventually fail: thermodynamics. Everything else is a story we tell ourselves about agency in a room whose layout is being designed by someone else.

We are running out of runway.
