Applications written in COBOL, RPG, etc. will be around forever because they offer older coders job security. Ever work at a company run on one of these systems? Through overstatement of risk and cost, these applications persevere. Trying to retire one is like laying siege to a fortress. RPG is a pretty cool language though, I never knew it was directly related to punch cards. Fascinating.
