Knobs Are Used In Many Places

Behind the volume Knob is a mechanical variable resistor that, when you turn them, changes the amount of power output to the speaker smoothly and accordingly. However, software development is getting faster and faster. Even if the mechanical variable resistor can be more miniaturized, it can't escape the fate of being replaced by a large scale. It is not that it is not easy to use, but the cost of the software solution is lower.

In 1999, audio engineer Tom Dewester built a radio that only interacted with the knobs, which was undoubtedly anti-trend at the time. People at that time used to use buttons and displays, just as people are used to using touch screens.

Today, knobs still exist on different devices. For example, high-end audio equipment, or Leica cameras, but often such equipment is not cheap, and is small.
