What happens when artificial intelligence doesn’t just change work but eliminates it? Not someday. Now.

Nicolas Chaillan served as the first Chief Software Officer of the U.S. Air Force and Space Force. He watched the shift happen inside the Pentagon—then built it himself, running thirteen AI agents for roughly $200 a day to replace work that once required a full team.

Replacement is a firsthand account from someone who built the systems, saw the disruption coming, and is now sounding the alarm. This is not a warning about the future. It’s a dispatch from the present. And a survival plan for your family.
