  1. Assessment: Can’t be checkedSaid

    Causal claim

    “Aside from Nvidia’s Jensen Huang, a brilliant and impressive CEO with considerable foresight, nobody was more responsible for Nvidia’s rise than Sam Altman, the relentless showman who runs OpenAI — and who repeatedly promised the moon.”

    Our reading: Apart from Jensen Huang, nobody was more responsible for Nvidia's rise than Sam Altman, the showman who runs OpenAI and who repeatedly promised the moon.

  2. Assessment: Can’t be checkedSaid

    Observation

    “It turns out this was authoritative bullshit. It sounded true and was said with confidence, but it was purely a bluff.”

    Our reading: Altman's January 2025 claim that OpenAI was confident it knew how to build AGI was a bluff.

    Observation

    “Altman didn’t actually know how to build AGI [artificial general intelligence] then, and probably still doesn’t.”

    Our reading: Altman did not know how to build AGI in January 2025 and probably still does not as of February 2026.

  5. Assessment: SupportedSaid

    Observation

    “Not an all out crash, but an unmistakable sign that its ascent has run out of gas.”

    Our reading: Nvidia's flat stock since August 2025 shows its rise has run out of gas, though it has not crashed.

  6. Assessment: Can’t be checkedSaid

    Forecast

    “My guess is that these stocks – and the reputation of OpenAI – will fall further, but either way it is already clear that the rockets will not reach the altitude so many people were hoping for.”

    Our reading: AI tech stocks such as Nvidia, CoreWeave and Oracle, and OpenAI's reputation, will probably fall further.
