Why AI Agents Should Query Existing Data Systems Instead of Building Vector Infrastructure

Summary

The article argues against the prevailing trend of building parallel AI-specific data infrastructure (vector databases, embedding pipelines, RAG systems) as a costly "AI centralization tax." Instead, it advocates for a federated approach where AI agents query data directly from existing systems using tool access, avoiding the need to duplicate and centralize data into vector stores. The author contends that most teams don't need complex vector infrastructure and should first consider letting AI agents access data where it already lives.

This is what I call the AI centralization tax. Not the cost of having a data warehouse, that's often justified. The tax is building a parallel AI-specific data infrastructure on top of what you already have: vector databases, embedding pipelines
Before building vector infrastructure, consider federation: AI agents with tool access to your existing systems. That's all most teams need.
Someone told you to pivot to AI. Add an AI layer. 'We need to be AI-first.'
So the playbook writes itself: collect data in a central place, set up a vector database, do some chunking, build a RAG pipeline, maybe fine-tune a model. Then query it. Ship the chatbot. Declare victory.
