Hey guys, just posted a video on the $30,000 AI system I'd build for any business before I built anything else. Cover why an AI-powered knowledge base is infrastructure not a tool, the four-layer architecture that makes it work, when to use NotebookLM versus Obsidian, the real math behind why this is worth $30K to a business every year, and the exact deployment sequence I'd use to roll it out. If you run an agency, this is the engagement you lead with. https://youtu.be/RvypDxHMD7Y
