Vector Database

RAG Is a Lie. You’re Just Building a Search Engine With Extra Steps.

The RAG hype cycle is a generational knowledge gap. Veterans see a renamed search engine with extra steps, while newcomers see a revolutionary pattern. The real value isn’t RAG itself, but the abstraction layer that lets non-search engineers leverage information retrieval without inverted indexesβ€”and that abstraction is both the gift and the trap.

99% of AI Apps Don’t Need a Vector Database. Here’s the Hard Limit.

For up to one million documents, brute-force search with plain NumPy is faster, cheaper, and simpler than a vector database. The hype around vector DBs has convinced developers to over-engineer for scale they don’t have. Start simple, and only migrate when your brute-force script actually breaks.
