The distinction between two main types of simplicity, those of parsimony and elegance, has been a long-standing philosophical topic [1].
In engineering, the so-called KISS principle (first coined as such in the early 20th century) has always had the implication of minimalism and implementation simplicity, in contrast to mere ease of use.
Fred Brooks wrote a famous paper in 1986 [2] perfectly describing the differences between accidental and essential complexity, and of the semantics of complexity management in software projects.
Hickey has said absolutely nothing spectacular, but his name comes up every time from the typing fingers of the historically illiterate whenever simplicity and ease of use are brought up.

Rich Hickey gained fame for this because he stated an idea very clearly and compellingly, this is non-trivial and should not be so flippantly dismissed as just recyling old ideas—all your ideas are recycled too.
+100 for this.
I knew about KISS, but almost every time I hear someone mention it they think about ease not simplicity. I will also definitely check out Brooks' paper.
While I understand your position, I believe a lot of this has been lost to the new generations of engineers and what Rich did is remind them of it.
Also note that english isn't my first language (I'm french Canadian) and even here in french the distinction is seldom made.
