What Are World Models? Their History and the $10 Billion Bet

「世界模型」究竟是什么？一文看懂其前世今生与百亿赌局

Jiqizhixin translated a MoE Capital blog tracing two world-model lineages. The article says more than $10 billion entered the category over 18 months, and cites DreamDojo as using 44,711 hours of first-person video pretraining to reach r=0.995 correlation with real-world robot policy outcomes.

Why it matters: HKR-H/K/R all pass: the hook is strong and the article gives concrete figures, but it is a compiled explainer rather than a new release. It fits the featured-threshold band for a strong commentary/tutorial.
