You use abstractions every day

Turn a steering wheel. Your hands make one simple movement. Underneath, the steering system changes the angle of the wheels.

Tap a name in your phone. You do not find a radio tower or route your voice across a network. The phone handles those steps.

Press a floor number in an elevator. You do not control the motor or release the brakes.

In each case, you use a simple control. A larger system handles the work beneath it.
