On the record

Open Settles on evidence
If there exist AI systems that can perform 8 of the 10 tasks below by the end of 2027, as determined by our panel of judges, Gary will donate $2,000 to a charity of Miles’ choice; if AI can do fewer than 8, Miles will donate $20,000 to a charity of Gary’s choice.

MET if The panel of judges mutually agreed by Gary Marcus and Miles Brundage determines that AI systems existed by the end of 2027 that can perform at least 8 of the 10 tasks listed in the 30 December 2024 post (movie comprehension, novel comprehension, biographies/obituaries, video-game mastery, legal briefs, 10,000+ line bug-free code, Pulitzer-caliber books, Oscar-caliber screenplays, Nobel-caliber discoveries, formalization of math proofs), where tasks need not have been actually attempted commercially but must be technically feasible with modest per-task cost (roughly $1 million of compute plus 10 person-weeks), and where the tasks are not performed by 10 completely separate bespoke systems. at any point, before 2027-12-31 23:59 (UTC).

The prediction doesn’t have to start here.

A call made on X, a podcast, YouTube, Substack, CNBC — or here — becomes the same locked record: the exact words, the original source, the date, and the test that settles it. You said it first? Now you can prove it.

Said on XPaste the post. We fetch it and confirm the account.
Said on a podcastPaste the episode or transcript. The quote is checked against it.
Said hereWrite it directly. The timestamp is the proof.

How it works

  1. Put it on the record. Make your own prediction, or paste a public source where someone else made one.
  2. Lock the test. Thonest works out what would settle it, by when, and from which source — and shows you that in plain English. You confirm before anything locks.
  3. See what happens. Predictions settle the moment their locked condition becomes conclusive. Nobody moves the goalposts afterwards, including us.

Why this is worth more than a screenshot

A screenshot proves nothing — anyone can fake one, and the post behind it can be edited or deleted. Every record here carries four things instead, each checkable by someone who thinks we’re lying.

1 · The source’s own wordsWe don’t take the submitter’s word for the quote. The platform is asked directly, and the exact wording must appear in what it returns — or the record is refused.
2 · An independent snapshotThe page is saved to the Internet Archive at capture time, on a server we don’t control. When that fails, the record says so rather than implying corroboration it doesn’t have.
3 · Anchored to BaseA fingerprint of the record and its locked test is written to a public blockchain. Change one character afterwards and the fingerprint stops matching — publicly, permanently.
4 · A contract that can’t edit itselfBatches are chained on-chain and the registry has no edit or delete function. Not “we won’t” — we can’t, and neither can anyone who buys us.

What we deliberately don’t claim: none of this proves a statement is true. Provenance shows where it came from; anchoring shows it hasn’t changed. Anyone who tells you a blockchain makes something true is selling you something. The full argument, including what could still go wrong →
