COBOL code, like any code, was written to embody certain business processes, and also to work around the quirks and blind spots of COBOL. And the people who understood those business processes are likely to be dead by now, and any documentation they wrote might be current and correct, or it might not. And very few people under the age of 60 have ever used COBOL in anger. So any legacy replacement project is going to have to encompass a big reverse-engineering effort, including analysis of a code base nobody is familiar with.

I'm old. A friend of mine is a fair bit older, getting into his late 70s. He knows COBOL but his main area of expertise is OS services, database tuning and assembler on old IBM and Fujitsu iron. Those are critical to keeping those old systems running well. He works half-time, is booked over a year out, and has a jaw-dropping daily rate. He also has a rider: one provision is that they have to tell him where he can smoke on-site, and if the answer is "nowhere," the deal is off. Also, he won't schedule any work that conficts with Burning Man, and he looks like a homeless guy. I brought him in on a consulting gig once. He did his bit, including an amazingly effective presentation to the C-levels (despite his profoundly non-executive appearance), and went his merry way. Saved us a fortune. You need people like that in order to have even a remote chance of success, and they're becoming exceedingly rare. Musk and his kiddies don't even know what they don't know.
