Developing a mechanical way of doing this from scratch is much more efficient than developing the entire stack of technology abstraction layers (from transistors to CPUs to computer engineering to LEDs to OSes to programming languages and runtimes, etc.) to achieve this digitally. Some spinning weals, gears, and springs are much much much more efficient!
