What is this schizo shit? Literally everything is derivative, nothing exists in a vacuum.
If you raised a human in a white void with no sights or sound his entire life then gave him a pencil he'd never draw anything other than random scribbles or himself.
The keyboard you type with came from typewriters, typewriters came from writing balls, writing balls came from printmaking and letter impressioning, impressioning was a way to speed up transcription which was done via writing, writing came from rune carvings and cuneiform, cuneiform came from pictography, pictography likely originated from cave paintings, cave paintings were renditions of what people saw in the real world.
You could do this for anything, from game mechanics to music to art movements.
