I'm not sure what you're saying. Do you honestly expect every PL researcher to all work on the same magical super-language? No- they're going to work on the problem in their area of expertise and create/modify a language to show off their ideas. Then a language like Scala or Haskell or Clojure can come along and improve on them or combine them. Every field works this way. That's why there is more than one particle collider, more than one drug for each problem, more than one theory of particle physics, more than one programming language. Your link talks about radical change over gradual change in computer science. It seems to support the idea of creating new and dramatically programming languages. The idea that "small" changes have large effects discourages the gradual modification of existing paradigms and languages.
