Citrix AI Hotsheet

AI Agents, Second Brains, and the Enterprise AI Gap


Listen Later

Welcome to the first episode of the Citrix AI Hotsheet. Brian Madden (futurist, Citrix) and Dave Brear (account technology strategist, Citrix) introduce the show and dig into how AI is actually entering the enterprise — not the way the tech accelerationists or the vendor podcasts tell it, but the way it's really happening inside the banks, hospitals, and regulated environments where most knowledge workers actually work.

Two main topics this week.

AI will use the apps humans already use. Brian's thesis: AI in the enterprise won't come from top-down rewrites of every system — it'll come from AI workers logging in and using the same desktops, browsers, and applications human workers already use. We walk through why computer-using agents are slow today (screenshots, frame by frame), the OSWorld benchmark showing AI now exceeds the median human at operating a computer, and recent research on semantic primitives (W3C accessibility, Windows UI Automation) that cuts token consumption by ~80%.

The rise of context vaults. Dave introduces the second concept: knowledge workers are quietly building "context vaults" — what most people call second brains — that compound their thinking with AI. It started for both of us as a folder of notes; now it's the most significant shift in how we work day to day. We talk about why this is a corporate blind spot, what the scale problems look like, and the experiment of connecting two second brains together over MCP so we can ask each other's AI what the other one thinks.
