Because of the impending death of critical thinking.
Technology is a double-edged sword for this as it disseminates more information than ever before to us, but that is information overload, and as such the ability to focus on lengthy complex texts is diminishing, simply because we have to wade through so much guff to get to the crux of the matter.
The fact a lot of this stuff is now residing behind paywalls isn't helpful either.
People know who they like, and if a person of influence says something, who are you to argue against them? And if you do argue the point you just get shouted down, so really, what's the point?
Critical thinking is on life support, and it's not gonna get any better.
All of this is IMO.
