The article draws a historical parallel between railroad expansion and the emerging AI stack: as railways became too complex for individual operators to manage safely, specialized roles and systematic oversight became necessary. This logic applies to AI systems—as models grow more capable and integrated, dedicated infrastructure, monitoring layers, and distributed governance structures become non-negotiable. The analogy reframes current AI debates from "will we need safety mechanisms?" to "what organizational and technical structures scale safety faster than the systems themselves."
