I'm interested in history, and it seems that nearly every Wikipedia page could have a "History" section... something that explains how the object, entity, idea, theory, etc. came into being, how it changed during its formative stages. Someone who's seriously interested in developmental everything (developmental biology, history of science, history of civilization, etc) may well try to add a History section to everything.
On the flipside, it's possible to speculate about the future of most things. While this is sometimes pointless prognostication, there's sometimes been serious thought put into what the future may hold.
However, it's important to not take this as a practice in triumphalism or predestination, or assume that just because one or more prominent nations are taking up some practice, that it's obviously the future. (eg. progressives often mentally take the position that "X policy is obviously THE future... regardless of what opponents think, they're just slowing down the inevitable". However, even if you're sympathetic to progressive causes, it's inevitable that progressives will be wrong about something... assuming that only they know the future, is bound to run into cases where they're wrong. Also, the fact that different cultures have different ideas about the future + history is written by the victor + no empire has lasted forever = means that the future may turn out to be very different from what any single group thinks it will be)
Other things are simply current trends taken to extremes... again, it's important to realize that a given trend does not mean that the trend will continue indefinitely, that it wouldn't stabilize somewhere before the furthest point.
