I don't know about this particular case but A-B tests often lead to this sort of thing (large images seem to really pull people in). We are moving into a world where software evolves into a niche. It doesn't need a reason why, and doesn't care if we understand it; it just works.
It doesn't need a reason why, and doesn't care if we understand it; it just works.
It also gets happily stuck and dies in a local optimum, being the simplicistic algorithm it is. We are moving (further) into a world where people stand for nothing, have no thoughts worth mentioning, and would do anything for money no matter how and where from; maybe we don't need to understand that, but it's pretty hard to unsee once you did.
