The Machines Picked an Operating System. It Wasn't Windows.
For fifty years the operating system argument was a matter of taste, and taste kept Windows on seventy percent of the world's desktops. Then computers got a new user. AI agents work through shell commands, text streams, and small tools chained together, and that describes a design philosophy written down at Bell Labs in 1978. The machines were never going to vote on familiarity. They compose with whatever was built for composition, and the gap between the two kinds of operating system is about to become the gap between working infrastructure and legacy.
