Watsonx: IBM's code assistant for turning COBOL into Java

Pretty much exactly. There are wizards at Project Zero doing reverse engineering of systems at the hardware microcode level. Our own kens shows up every few weeks with transistor level explanations of devices whose designers are long since retired.

And we're supposed to believe that no one in the world can figure out a batch-processed COBOL accounting system? Please. The talent is there, it's just that no one responsible for these systems wants to hire at that level. But in extremis they will, and the world will survive.
