Responding on LinkedIn to researcher Abdelaziz Testas — author of 'The Battle for World Models,' who said LeCun's lecture left the impression he invented the concept and said little about predecessors including Jürgen Schmidhuber — LeCun traced world models back to 1950s optimal-control theory. Single-source and reputational rather than technical, but it lands while world models are being positioned as the pre-training objective that replaces VLM-style pipelines, so who owns the lineage is about to matter commercially.
