Word vs World: Commenters Cage Match
Experts Have World Models. LLMs Have Word Models
Experts say AI thinks in words, not reality — comments erupt
TLDR: A provocative essay says AI chats in words, not real-world understanding, and argues we need models that simulate people and pushback. Commenters split: purists say language can’t capture reality, pragmatists back multimodal fixes, and builders reject chess analogies—making adversarial reasoning the next must-have for useful AI.
An essay just poked the AI beehive: experts have world models, chatbots have word models. Translation: today’s bots can sound smart, but they often miss the messy human context—like how a “no rush” Slack ping gets buried. The editor swyx jumped in, and the thread exploded.
The strongest camp? D-Machine’s crowd shouting, “It’s language, not reality.” They argue words can’t capture the full world—much of speech is persuasion, convention, or outright fantasy. On the other side, naasking’s crew says the bots do have a scrappy world model: words correlate with reality, so it’s patchy, full of holes, but fixable with multimodal upgrades like vision and audio. Meanwhile, measurablefunc swings a chair into the ring: stop comparing this to chess, because programming and real life don’t have neat rules or win conditions.
There’s industry name-dropping too: multi-agent “world games” from DeepMind, ARC-AGI, and Waymo got tossed around, with fans saying the age of brute-force scaling is giving way to actual research. And yes, jokers arrived: darepublic’s “Large embedding model” meme cracked everyone up. Verdict: the community isn’t buying pure word tricks anymore—they want AI that predicts people, incentives, and pushback. AIE tickets? Suddenly looking spicy. Bring popcorn for the panel debates.
Key Points
- •The article defines three active threads in world model research: 3D/video models, latent-space representation models (JEPA family), and multiagent/adversarial world models.
- •It focuses on multiagent world models that track theory of mind, anticipate reactions, and operate in adversarial settings.
- •Benchmarks by DeepMind, ARC‑AGI, and Code Clash model adversarial reasoning as games to study strategy and information dynamics.
- •The author argues that failures of LLM outputs often stem from insufficient “simulation depth,” not merely prompting or general intelligence.
- •A workplace messaging example illustrates that effective action requires modeling recipient heuristics, bounded asks, and clear stakes, emphasizing dynamic environments.
