Software has an unfortunate attribute (compared to hardware) where it's largely bound by what users will tolerate as opposed to what practically is possible.

Imagine Ford, upon the invention of push-button climate controls, just layered those buttons on top of the legacy sliders, using arms and actuators so pressing "Heat Up" moved an actuating arm that moved that underlying legacy "Heat" slider up. Then when touch screens came about, they just put a tablet over those buttons (which are already over the sliders), so selecting "Heat Up" fired a solenoid that pressed the "Heat Up" button that moved the arm to slide the "Heat Up" slider.

Ford, or anyone else doing hardware, would never implement this or it's analog, for a long obvious list of reasons.

But in software? That's just Thursday. Hence software has seemed stuck in time for 30 years while processing speed has done 10,000x. No need to redesign the whole system, just type out a few lines of "actuating arm" code.
