The world is independent of how we care to talk about it. If we find the old ways not longer are sufficient, adopting new ways just means we can improve our discourse. Sometimes those results materialize. Sometimes they don't. In a overly simplified environment they are more likely to happen in line with simplistic notions of cause and effect. In more chaotic environments causes may not even come close to a particular effect. In short, cause and effect was handy when we believed in the billard ball universe, but we have out grown it.
