PERSON
Joscha Bach
The cognitive scientist who built a mind rather than merely theorized one—architect of the MicroPsi cognitive architecture, author of the proposition that consciousness is a simulation that simulates itself, and the clearest voice on why our most powerful AI systems are intelligence without agency, model-making without a self.
Joscha Bach is the rare thinker in the AI conversation who has actually tried to construct the thing everyone else debates, and the attempt gives his analysis a weight that armchair philosophy cannot match. A cognitive scientist trained at Humboldt and Osnabrück, he spent years building MicroPsi, a running cognitive architecture based on the
computational theory of mind—specifying, in enough detail to implement, the motivational core, the emotional modulation, the self-model, and the integrated agency that he believed any genuine mind must possess. This background produces his distinctive double vision: he can grant the large language models their genuine achievement, because he recognizes from his own work the hard problem of relevance and association that the transformer architecture cracked, and simultaneously insist that they remain intelligence without a self, model-making without the motivational architecture that would make them agents. His most unsettling claim, developed over a decade
