If Perl 6 were a centrally managed and funded effort to create a popular language, I would a agree that the one who funds it would look at adoption numbers and time spent, and declare it sunk cost, and try to achieve their objectives through other means. But everybody who's working on Perl 6 does it because they enjoy it, learn by doing it etc. Why should they declare it a failure? Usage numbers are slowly, slowly creeping up, and working with and on Perl 6 can be real fun. If I'd work on it regardless on how much of my previous time I invested in it, why should I even consider sunk costs?
