> which turns components that once were hardware into a software program this is a fun one, because there is no shortage of knobs and buttons, just chips, and knobs don't need chips to work. Even if you do need a chip for it to work (eg. rotary encoder to canbus), most of them are still available, because the "old tech" is good enough for them (compared to newer, smaller transistor sizes, needed for modern cpus to process a lot of data - eg graphics cards, modern cpus and even touchscreen radios for cars).
