The thesis is deliberately provocative, which makes it useful. RAG is not simply dead, but the old chunk-embed-rerank default is under pressure from larger contexts, agentic retrieval loops, and document-native workflows.
I would keep this as a debate starter, not a doctrine. The production question is still which retrieval shape gives the model the right evidence at the right cost with inspectable failure modes.
