Good, we need more functional programmers actually solving real problems. But please put your skills to work in an industry other than investment banking.
There are lots of companies outside of investment-banking using functional programming. Bluespec, Galois, TypLab, are all serious Haskell users. Larger companies such as AT&T, Facebook, and Google have all used Haskell for various projects. If you look a bit further afield, there are even more companies using F#, Caml, and Erlang. I use Caml almost exclusively in my day job at Vector Fabrics – which is poles apart from investment banking. (And yes, we're always interested in hiring good functional programmers.) If you want a FP job outside of investment banking, keep an eye on the CUFP website and the FP mailing lists. Opportunities abound! Wouter
