It's possible, but I think there's also something akin to the Anthropic Principle that affects what sort of articles get the most views and links- if the authors didn't think big change was inevitable, they wouldn't write the articles, or the much more sober and realistic articles that they would write instead wouldn't get nearly so many views and links in aggregators like HN. The nature of the medium favors people making exciting predictions (that might even come true, who knows), not people throwing cold water on other people's exciting predictions (who are more likely to be correct but don't prompt nearly as much sharing and discussion).
