Viral claim: Stanford finds dopamine-like reward neurons emerging inside LLMs

Viral claim of an emergent dopamine-like reward subsystem in LLMs
A widely shared thread claims Stanford researchers analyzing LLM hidden states found:
- A sparse set of "value neurons" that anticipate answer quality
- A second set acting like human dopamine neurons—spiking when outcomes beat expectations, dropping when they fall short
- The architecture was never programmed, emerging spontaneously during training
Caveat: this arrives via heavily sensationalized secondhand retelling ("terrifying!"); the underlying paper hasn't been verified—wait for the primary source.
