Funny you mention it... almost replied to the post earlier saying that if I were to bet my career on a single language it would certainly be COBOL. Not glamorous, but it runs critical infrastructure and schools aren't exactly pumping out mainframe programmers.

That said, I have not and would not recommend betting on a single language. Being polyglot has its own advantages.

edit: any ideas for a first project with Go? Any place it's particularly well suited for?

edit: I re-emphasize my 2nd paragraph, "I have not and would not recommend betting on a single language"

I don't think that's a very good bet. There is still a lot of COBOL sticking around, but there are essentially zero new COBOL projects being started while there are a non-zero number of COBOL projects being replaced with other languages, so COBOL use is ultimately trending downward. You are essentially betting that COBOL developers die out faster than COBOL itself does.
