Proliferation of programming languages.

Maybe it's just me, but lately I'm feeling a little bewildered for our apparent need to keep inventing programming languages and frameworks. A short list, just consisting of my use, exposure, and/or interest: Machine Language, Assembly Language, Basic, Pascal, Lisp, C, Fortran, PERL, Python, TCL, C++, Java, Javascript, Spring, Ruby (on Rails), Smalltalk, Groovy, Grails, Trails, Erlang, Haskell, Scala, Clojure. Makes it challenging for someone with a short attention span to stick to one language long enough to get things. done.
