As fascinating and powerful as AI systems like ChatGPT and Claude have become, they still possess what I affectionately (and sometimes frustratingly) call a “frozen brain problem.” Their knowledge is permanently stuck at their last training cutoff, causing them to occasionally hallucinate answers—AI jargon for confidently stating nonsense.
RAG fundamentally reshapes what we thought possible from AI by handing these brilliant-but-flawed models a crucial upgrade: an external, dynamic memory. Imagine giving our hypothetical brilliant person access to an extensive, always-up-to-date digital library—now every answer can be checked, validated, and supported with actual data. It’s like turning that closed-book exam into an open-book test, enabling real-time, accurate, and trustworthy answers.
The stakes couldn’t be higher. We’re moving quickly into a future where businesses, hospitals, law firms, and schools increasingly rely on AI to handle complex information retrieval and decision-making tasks. According to recent market analyses, this isn’t a niche upgrade—it’s a seismic shift expected to catapult the RAG market from $1.96 billion in 2025 to over $40 billion by 2035. Companies who fail to embrace RAG risk becoming like video rental stores in the Netflix era: quaint, nostalgic, but rapidly obsolete
