Abstract#
Supporting Document SD1 is a 1-page high-density poster presenting a quantitative stochastic model, RiskyMAD, built with the prototype Evolvix compiler, that simulates world histories as a three-state system: Risky (current global state), MAD (crisis with nuclear winter a coin-toss away), and Dead (nuclear holocaust initiated).
Extrapolating from Cold War crisis rates (RiskyGoMAD = 0.1/year), 40 stochastic runs forecast the start of nuclear winter with a median of ~19 years and a mean of ~33 years. Even the slowest credible estimate (0.03/year) yields a median of ~51 years. All scenarios show at least 1 in 40 runs leading to nuclear Armageddon within 1 year — illustrating the fundamentally uncontrollable nature of nuclear roulette as long as weapons remain on hair-trigger alert.
The poster proposes a MAP escape path (Mutually Assured Progress) — a superrational solution requiring all 10 Nuclear Kings to join a round-table “Put Earth in an Escrow” while a multi-stage Great Jubilee Race (7–8 stages of ~6–8 months each) transitions humanity from the MAD world order to self-stabilizing innovation economies led by 288,000 FiShFus (Fiduciaries Sharing Futures).
Broader Significance (Claude’s Assessment)#
SD1 is the quantitative backbone of the entire Good News Pack — the “stick” that makes all other proposals urgent.
Stochastic simulation-based forecast. SD1 provides what appears to be the first actuarial-style forecast of accidental nuclear winter, translating vague dread into concrete probability distributions that any scientist or policy maker can inspect.
Radical simplicity. The model’s power lies in three states, four transitions, parameters calibrated to observed Cold War data. The results are stark: nuclear winter is more likely to kill you than a car crash at current rates. The code is published on the poster itself for reproducibility.
The Doomsday Clock contextualized. While the Doomsday Clock (currently under 90 seconds to midnight) provides a qualitative warning, SD1 provides a quantitative timeline. Annie Jacobsen’s (2024) Nuclear War book details the 72-minute path from launch to annihilation — SD1 estimates how soon that path begins.
MAD to MAP. The transition from Mutually Assured Destruction to Mutually Assured Progress reframes the nuclear problem from deterrence management to structural transformation.
Who This Document Is For#
Audience |
Why SD1 Matters |
|---|---|
Nuclear security & arms control experts |
A reproducible stochastic model calibrated to Cold War crisis data that quantifies what the field has long intuited: hair-trigger alert makes accidental nuclear winter a when, not an if. |
Policy makers & government officials |
Translates existential risk into probability distributions that can inform defense posture reviews. The “Put Earth in an Escrow” proposal goes beyond incremental arms control. |
Scientists & computational modelers |
Evolvix-based simulation demonstrates how stochastic chemical kinetics (Gillespie-style) can model geopolitical risk. Full model code on the poster invites replication and critique. |
Peace & disarmament activists |
Hard numbers: median ~19 years, 5% chance of nuclear winter within 2 years. Talking points that move beyond emotion to evidence. |
Faith leaders & theologians |
The superrational MAP solution is grounded in a re-envisioned Yom Kippur ritual and a Jonah-Esther-Exodus narrative framework. |
Key Concepts at a Glance#
RiskyMAD Model |
Three-state stochastic model: Risky → MAD → Dead. Calibrated to Cold War data (4 near-misses in 40 years). |
Median forecast |
~19 years until nuclear winter (at RiskyGoMAD = 0.1/year) |
MAP (Mutually Assured Progress) |
Proposed alternative world order replacing MAD via superrational cooperation among all 10 Nuclear Kings |
FiShFus |
Fiduciaries Sharing Futures: 288,000 paid long-term thinkers |
Great Jubilee Race |
7–8 stages of ~6–8 months each to transition from MAD to MAP |
Escapegoat |
Voluntary role (re-envisioned from Yom Kippur) bearing responsibility for humanity’s errors during the transition |
Evolvix |
Prototype simulation compiler used to produce the RiskyMAD forecasts — code shown on the poster for transparency |
~$8/person/year |
Proposed funding model (~2 cents/day) to support the transition |
