I hope you understand that just because a proposed explanations makes intuitive sense, it doesn't automatically have to be right.

Edit - it seems there's evidence that this intuitive explanation is wrong, see the article linked here: https://news.ycombinator.com/item?id=50146562

This is why I like to remind myself that the world is much more interesting than I often think, which is why the drive to jump to simple and boring explanations can often be a trap.
