I can actually see that as being real. There is a lot of legacy code out there (especially in larger corporations) and, while these languages are rarely featured in the news, many people are required to use them at work.
I know someone whose job is to maintain COBOL code for the State of Texas. Government organizations have even more difficulty upgrading IT infrastructure than large corporations do, and there are a lot more of them that can survive a lot longer than there are large corporations.
Just to put things in perspective a bit further.
