The market is the arbiter of commercial success, and nothing else. In particular, the market has nothing useful to teach us about science or mathematics. I am a supporter of markets in general, and the EMH as well, at least in its weak form. But one has to understand their limitations: they are in essence an elaborate form of popularity contest.

And: markets change their minds. It is easy to adapt your "the market has spoken" argument to a circa-1985 argument that says we should not pursue C++ (or anything else) because "the market has spoken" and chosen C: it is fleshed out, implemented, and it is what the market picked.

Really? How many academic papers from the last ten years of computer science research have you read? Nothing in there except whining? Or by "coming out" do you mean releasing a product? Is commercial activity the only legitimate form of human activity?

Stem cell research has been a commercial failure; I guess we should abandon that, eh? Fusion power? No one's made a billion dollars from the Calculus of Inductive Constructions; I guess it's worthless then.
