Hype still sells and we still idolize people though. Businessmen such as Steve Jobs or (early) Elon Musk curate an image of themselves as a “genius”, which leads to popularity of their products and influences trends and opinions in specific fields.

Really though, no single person did or invented anything alone.

The Upright Thinkers by Leonard Mlodinow is a good pop-sci book that carries that point throughout.
