Claims from this post (14)

In the order they appear in the post. Each quotation is the speaker’s words in this post. A label such as “Supported” or “Can’t be checked” is the claim’s current assessment; its page has the evidence and the reasons.

  1. Assessment: Can’t be checkedSaid

    “Artists are presumably getting really screwed here.”

    What we tested: Artists are probably being badly harmed by the way Sora was trained.

  2. Assessment: Can’t be checkedSaid

    “I would not at all be surprised if there also had been lots of training on YouTube visited, and various copyrighted materials.”

    What we tested: Sora may well have been trained on lots of YouTube video and various copyrighted materials.

  3. Assessment: Can’t be checkedSaid

    “In my view, these claims — about AGI and world models — are hyperbolic, and unlikely to be true.”

    What we tested: Claims that Sora amounts to AGI, vindicates scaling laws, or constitutes a world model are hyperbolic and unlikely to be true.

  4. Assessment: SupportedSaid

    “That gross violation of spatiotemporal continuity/failure of object permanence is not a one-off, either; it’s something general.”

    What we tested: Sora's failures of spatiotemporal continuity and object permanence are general, not one-off.

    What happened: OpenAI describes spontaneous appearances as a model weakness associated with a class of scenes, rather than as one isolated video defect. This directly supports recurrence without establishing how often it happens. (OpenAI, )

  5. Assessment: SupportedSaid

    “We will, I am certain, see more systemic glitches as more people have access.”

    What we tested: As more people gain access to Sora, more systemic glitches will be found.

    What happened: The release expanded access beyond the February preview group, satisfying the antecedent. (OpenAI, )

  6. Assessment: UnresolvedSaid

    “Because the glitches don’t stem from the data, they stem from a flaw in how the system reconstructs reality.”

    What we tested: Sora's glitches don't stem from the data; they stem from a flaw in how the system reconstructs reality.

  7. Assessment: UnresolvedSaid

    “And importantly, I predict that many will be hard to remedy.”

    What we tested: Many of Sora's physics glitches will be hard to fix.

  8. Assessment: UnresolvedSaid

    “More data won’t solve that problem.”

    What we tested: More training data will not solve Sora's hallucination-like physics glitches.

  9. Assessment: SupportedSaid

    “Sora is not a solution to AI’s longstanding woes with space, time, and causality.”

    What we tested: Sora does not solve AI's longstanding problems with space, time, and causality.

    What happened: The motion weakness directly establishes an unresolved physical-consistency problem. The surrounding limitations text also describes errors in spatial instructions, event trajectories, and consequences of interactions. (OpenAI, )

  10. Assessment: Can’t be checkedSaid

    “If a system can’t at all handle with the permanence of objects, I am not sure we should even call it a world model at all.”

    What we tested: If a system can't handle the permanence of objects at all, Marcus is not sure it should even be called a world model.

  11. Assessment: Can’t be checkedSaid

    “Sora is fantastic, but it is akin to morphing and splicing, rather than a path to the physical reasoning we would need for AGI. It is a model of how images change over time, not a model of what entities do in the world.”

    What we tested: Sora is akin to morphing and splicing of images, not a path to the physical reasoning needed for AGI.

  12. Assessment: Can’t be checkedSaid

    “As a technology for video artists that’s fine, if they choose to use it; the occasional surrealism may even be an advantage for some purposes (like music videos).”

    What we tested: As a technology for video artists Sora is fine if they choose to use it, and its occasional surrealism may even be an advantage for some purposes such as music videos.

  13. Assessment: Can’t be checkedSaid

    “As a solution to artificial general intelligence, though, I see it as a distraction.”

    What we tested: In Marcus's view, Sora is a distraction as a solution to artificial general intelligence.

  14. Assessment: SupportedSaid

    “And god save us from the deluge of deepfakery that is to come.”

    What we tested: A deluge of deepfakes is coming, enabled by systems like Sora.

    What happened: IWF assessed 3,443 realistic AI-generated abuse videos in 2025, versus 13 in 2024. Its accompanying observations include fabricated videos of known victims, establishing substantial harmful impersonation rather than merely benign synthetic production. (Internet Watch Foundation, )
