I'm surprised that the guys worried about one or more "collapses" aren't more into COBOL. Because when something heavy and hard hits, all that's left will be roaches, COBOL and Perl scripts.

But seriously, I bought some old COBOL books recently, and was meaning to get more into it. Not because of some job situation, but it seemed different enough, in a "cozy" manner. I could get away from the Algol-ish day job languages with something blatantly more concise (extremely functional, esolangs or APL), but that's more the "puzzle" aspect where COBOL might be more the "knitting" approach.
