The core argument: the knowledge-acquisition bottleneck, brittleness at ontology edges, complexity catastrophe, and hardware economics that killed expert systems are all present in modern LLM-based agents — just wearing different clothes. RAG is framed as a modern Knowledge Principle implementation, and agentic engineering is positioned as the discipline needed to avoid repeating the AI winters. ## Full article daily.dev links to this article rather than hosting it.
