If cobol is so great, why do Amazon and google run exactly 0 lines of it? There is a cost (vastly increased development time, inflexibility) to sticking with cobol, and it may be so great someday that it'll drive the companies that use it out of business. Just give newer companies 15 years after the current economic crisis is over and free competition and you'll see the difference.
