Yeah, it seems a natural consequence of the combination of vast amounts of recent content with the fact that people mostly want recent content. To pick one trivial example from yesterday, if I'm looking for help with an interface issue with some current version of a program, forum posts from 10 years ago are probably not useful.
Information that people regularly access for whatever reason will tend to remain relatively visible. But, yeah, relatively obscure older content is just going to get drowned out unless you know exactly where and how to look. One might argue with Google's criteria around relevance. However, that older information is going to get harder and harder to find just in the natural course of things.
