A non-human mind produces knowledge beyond us
An artificial system originates a scientific or mathematical idea, not merely a search that exhausts the cases: the key construction or proof idea comes from the system and not from its operators, and the record says so. A brute-force proof that a solver ground out is a tool's work; a construction nobody had thought of is a mind's. I had to decide how strictly to read "not from its operators", and the answer I came to is this: when the operators built the search frame and the scoring rule, then the idea is theirs, even if the system found the answer. On that reading the machine-found constructions of 2022 to 2025 that beat the best human ones do not meet it: not FunSearch, not AlphaTensor, and not AlphaEvolve for now, since no peer-reviewed record yet says its key idea was the system's. Until October 6th, 2026 this page read the test more loosely and counted those results as plausibly meeting it.
The test: what counts as it having happened
A result in mathematics or the natural sciences whose key construction or proof idea was generated by a learning-based or search-based artificial intelligence system and not specified by its operators, acknowledged as such in the peer-reviewed record, that is verified by machine checking or by experiment and is acknowledged in that record as beyond what human researchers had produced. An exhaustive case check or a satisfiability proof whose idea was the operators' does not count.

The odds, by how long I live
| baselineto 2071 ± 8 | moderateto 2080 | strongto 2095 | radicalto 2136 | openno deadline |
|---|---|---|---|---|
| 95% | 96% | 97% | 98% | 98% |
Each column is a different guess at how long I live, from current trends (baseline) to open-ended. The number is the chance this happens before that deadline, assuming everything it depends on happens first. As of September 20th, 2026.
Why these numbers: Re-estimated September 20th, 2026 against the machine-originated-idea wording: at least two published results from 2023 to 2025 (a search-based system's new constructions for a long-open combinatorial problem, and a later system's improved matrix-multiplication and packing bounds) appear to meet it on their face, and the record in each case says the construction came from the system, so the remaining doubt is whether a scan finds the wording met in so many words. Proposed by Claude September 20th, 2026, I accepted. Note added October 6th, 2026: this reason was written before the strict reading settled the same day, under which those results do not meet the criterion (docs/definitions.md, decision log). The numbers are held as they are until the review after December 31st, 2026. Proposed by Claude, approved by me.
What this one is worth
Nothing. The headline number does not rest on this step at any remove, so however it turns out, the chance that I live and work off Earth does not change. That is not a judgement that it does not matter. It is what the tree says: this step feeds a tier above the one the headline asks about, or sits beside the equation rather than in it.
What the ledger says about this step
- OpenAI posted hundreds of machine-generated maths results on October 6th, 2026, but none is peer reviewed yet, so the first Contact Clause rung stays where it was 2026-10-11 Widely reported, moved nothing · this step was read against it and did not move · found by the weekly web scan
- The first rung of the Contact Clause was rewritten to ask for a machine-originated idea, because as written it had already been met by a brute-force proof in 2016 2026-09-20 The tree itself changed

2026-11-01 No change
Verify claims, no change: AlphaEvolve mathematics paper is still arXiv 2511.02864 with no journal acceptance found; AlphaTensor facts hold (Nature, October 2022, 47 multiplications mod 2); the Erdős unit-distance disproof is still preprints only (arXiv 2605.20695 and an OpenAI note) with no journal record found. Separately, a secondary report says OpenAI announced on August 1st, 2026 an internal model 'Astra' that made progress on 10 open problems with Lean-formalized proofs, outside the window and not a peer-reviewed record.

2026-10-25 Ruled
Verify claims: AlphaEvolve's mathematics paper is still the arXiv preprint 2511.02864 (November 3rd, 2025) with no journal acceptance found; the OpenAI Erdős unit-distance disproof (announced May 20th, 2026) has arXiv papers and outside checking but no journal publication found; AlphaTensor's Nature paper of October 5th, 2022 is unchanged and stays unresolved under the strict reading. New this week: Google DeepMind's AlphaProof Nexus is reported as published in Science on October 8th, 2026 (nine of 353 open Erdős problems and 44 of 492 open OEIS conjectures proved, every proof machine-checked in Lean), a peer-reviewed record the node's list does not yet name. I could not open the Science paper (science.org returned 403) or the arXiv preprint, so I cannot say whether it credits the key ideas to the system or calls the results beyond human work.
For me: No move made. Proposal: add AlphaProof Nexus (Science, October 8th, 2026; arXiv 2605.22763; Lean proofs at github.com/google-deepmind/alphaproof-nexus-results) to C1's verify list as a candidate, to be read against the criterion by the next scan. The criterion needs the peer-reviewed record to say the key idea was the system's and that the result goes beyond what humans had produced; secondary coverage describes Gemini devising the proof strategy and Lean checking it, and says the nine Erdős solutions are not all full solutions of the original problems (Erdős 12 is only partly solved), so it may well not meet the bar. I could not fetch the primary pages (science.org 403; arXiv not fetched), so I am not proposing a correction, only that the paper be read directly.
Taken off my list on November 1st, 2026, by a later scan.

2026-10-18 Nothing new
Verify claims: AlphaEvolve's mathematics paper is still the arXiv preprint 2511.02864 (submitted November 3rd, 2025) with no journal acceptance found, so no peer-reviewed record yet says the construction was the system's. The OpenAI Erdős unit-distance disproof (announced May 20th, 2026) has arXiv papers and outside checking but no journal publication found. AlphaTensor's Nature paper of October 5th, 2022 is unchanged (47 multiplications for four-by-four matrices modulo 2) and stays unresolved under the strict reading. Also seen: Axiom Math says five journals have accepted proofs its prover made (Axios, May 26th, 2026, company claim, page could not be fetched) and OpenAI's Astra results (August 2nd, 2026) are unrefereed; neither shows a peer-reviewed record crediting the key idea to the system as beyond human work.

Claims still to be checked
- Candidates for resolution under the September 19th, 2026 wording, written from memory on September 20th, 2026 and checked against the published record from then on: FunSearch (Nature, December 2023), new constructions for the cap set problem found by a language-model-guided search and described by the authors as beyond the best known; and AlphaEvolve (May 2025), an improved algorithm for multiplying four-by-four complex matrices and improved bounds on several open problems including the kissing number in eleven dimensions. Updated October 6th, 2026 (proposed by Claude, approved by me): FunSearch is settled by the strict reading decided the same day, because its operators wrote the scoring function and the program frame, so the idea is theirs; do not check it again until the review after December 31st, 2026. AlphaEvolve stays open to check, narrowed to one question: does a peer-reviewed paper now say its key construction came from the system and not from its operators? Neither is resolved here: under the Contact Clause null rule (docs/proposal-contact-clause-null-rule-2026-09-19.md) the criteria were written before the evidence was read against them, and the scan does the reading. The wording before October 6th, 2026 is kept in this node's revisions. Checked October 8th, 2026 by the weekly scan: the AlphaEvolve mathematics results are still a preprint (arXiv 2511.02864, posted November 3rd, 2025) and no journal acceptance was found, so no peer-reviewed record yet says the construction was the system's; the question stays open for later scans.
- Candidate for resolution under the September 19th, 2026 wording, added October 6th, 2026 at the first scan audit (my decision) and to be checked by each scan against the published record: AlphaTensor (Nature, October 2022), a reinforcement-learning system that found matrix-multiplication algorithms beating the best known for several sizes, including 47 multiplications for four-by-four matrices in arithmetic modulo 2, described by its authors as going beyond the best human-designed algorithms. Not resolved here: at the same audit I decided that clause (a), 'not specified by its operators', is read strictly, so a search frame and scoring rule built by the operators make the idea theirs, and on that reading neither AlphaTensor nor FunSearch resolves this step; the reading may be looked at again after December 31st, 2026. Facts checked October 8th, 2026 by the weekly scan: Nature, October 2022, 47 multiplications for four-by-four matrices in arithmetic modulo 2, as stated; it stays unresolved under the strict reading.
- Candidate for resolution under the September 19th, 2026 wording, added October 12th, 2026 on the weekly scan's flag of October 8th, 2026 (proposed by Claude, approved by me at the merge) and to be checked by each scan against the published record: a disproof of Erdős's unit-distance conjecture by an internal OpenAI model, announced about May 20th, 2026 and checked by outside mathematicians, which the scan read as a construction the model built itself (as reported by Scientific American, https://www.scientificamerican.com/article/ai-just-solved-an-80-year-old-erdos-problem-and-mathematicians-are-amazed/). Not resolved here: the scan found no peer-reviewed record of it, and the criterion asks for one that says the key idea was the system's and that the result goes beyond what human researchers had produced. The question for each scan is whether a journal has published it and what that record says about who had the idea.
