One of the guys that article cites clearly has some less savory beliefs about race (that I disagree with, people are mostly the same the world over) but man did he do a good job predicting the ideological battles lines of 2020 for someone writing in 2012.
Read "Kindly Inquisitors" if you'd like a very thoughtful defense of Enlightenment ideas as it pertains to knowledge and speech. If you're impressed with someones prediction from 2012 then you'll be more amazed with someones analysis from 1995. This book is a classic and the author, Jonathan Rausch is highly respected.
It wasn't so much a prediction as an observation of an incipient trend that went dormant and re-emerged. Post-modern attacks on Enlightenment ideals such as free thought and free speech were common on campuses in the late 1980s and early 1990s, then went dormant in the mid-90s, then re-emerged in the early 2010s.
Soviet Union collapsed and China started retooling for capitalism. Foreign propaganda dropped off.
Meanwhile in the US the 90s boom was kicking off and the US was exploding into global hegemony. Why protest and fight the man when communism was collapsing and there was more to gain from getting on board the winning team.
In other words, the trend dropped off externally and internally there were a lot of reasons to assume that history was in fact ending and to jump on board with MURICA and FREEDOM.
