Yeah, I read the article.

They’re MASSIVELY handwaving a lot of detail away. Moreover, they’re taking the “we’ll fix it in post” approach by suggesting “we can just run an armful of security analysis software on the code after the system spits something out”. While that’s a great sentiment, you (and everyone considering this approach) needs to consider that complex systems are pretty much NEVER perfect. There WILL be misses. Add this to the fact that a ton of organizations that still use COBOL are banks - which are generally considered fairly critical to the day-to-day operation of our society, and you can see why I am incredibly skeptical of this whole line of thinking.

I’m sure the IBM engineers who made the thing are extremely good at what they do, but at the same time, I have a lot less faith in the organizations that will actually employ the system. In fact, I wouldn’t be terribly shocked to find that banks would assign an inappropriately junior engineer to the task - perhaps even an intern - because “it’s as simple as invoking a processing pipeline”. This puts a truly hilarious amount of trust into what’s effectively a black box.

Additionally, for a good engineer, learning any given programming language isn’t actually that hard. And if these transition efforts are done in what I would consider to be the right way, you’d also have a team of engineers who know both the input and output languages such that they can go over (at the very, very least) critical and logically complex areas of the code to ensure accuracy. But since this is all about saving money, I’d bet that step simply won’t be done.
