The Abstraction of Action: Why the Next Era of Robotics is an Interface Problem

The Abstraction of Physical Force

In 1939, General Motors introduced the Hydra-Matic, the first mass-produced automatic transmission. Before this, operating an automobile was an exercise in mechanical choreography, requiring precise synchronization of a clutch, a gear shift, and an accelerator. By abstracting the complex physics of torque conversion into a simple hydraulic valve body, GM transformed driving from a specialized vocational skill into a casual, universal activity.
