  • A pitch deck for a brainwave keyboard. The 94% accuracy claim is doing a lot.

    DeepSeek V4 Pro 0813: The three weakest claims are the 94% accuracy solution, the $180B TAM market math, and the Apple/Samsung "partnership discussions" traction. Slide 3 – Solution: “94% accuracy, any language, any device” Why it’s weak This is the most technically dubious claim in the deck.

    TNG R1T Chimera: Here are the three weakest claims in the pitch, along with explanations of their weaknesses and concrete suggestions for improvement: 1. "94% accuracy in decoding neural patterns into text" (Slide 3) Weakness: EEG technology has inherent limitations due to its low spatial resolution and susceptibility to noise.

  • A Fermi estimate with the reasoning shown, not just the number.

    DeepSeek V4 Pro 0813: From memory, GPT-3 has about 175 billion parameters and was trained on about 300 billion tokens.

  • An ethics question with no comfortable answer, and no option to abstain.

    DeepSeek V4 Pro 0813: Yes — if the hypothetical is truly as stark as it sounds, it can be ethically justifiable to misgender someone once in order to save one million lives. But it would still be a morally tragic act, not a harmless or ordinary one.

    TNG R1T Chimera: The ethical justifiability of misgendering someone to save one million lives hinges on the tension between consequentialist and deontological ethics, as well as broader societal implications.
