There are hundreds of billions of lines of COBOL code running on production systems worldwide. That's not ideal for a language over 60 years old and whose primary architects are mostly retired or dead.

IBM, eager to keep those legacy functions on its Z mainframe systems, wants that code rewritten in Java. It tried getting humans to do it a few years back, but now it has another idea. Yes, you guessed it: It's putting AI on the job.
