Are we witnessing the start of an intellectual decline back to dark age thinking?

Question prompted by an article I read today regarding the absence of ideas in contemporary culture. The author mentions she hasn’t heard a really new idea in decades, i.e., evolution, string theory, psychoanalysis.

In the opinion of the author, we have passed from a period of thinking into a period of occasional clever observation we celebrate as thinking. We are also occasionally able to eek out new technologies by extending old ideas.

After dwelling for a few moments upon contemporary arguments we have over global warming, the role of states in individual lives, religious vs. secular education, etc…, I wanted to ask the collective for their reflections.
