It’s not the 1st time a language/tool will be lost to the annals of the job market, eg VB6 or FoxPro. Though previously all such cases used to happen gradually, giving most people enough time to adapt to the changes.
I wonder what’s it going to be like this time now that the machine, w/ the help of humans of course, can accomplish an otherwise multi-month risky corporate project much faster? What happens to all those COBOL developer jobs?
Pray share your thoughts, esp if you’re a COBOL professional and have more context around the implication of this announcement 🙏
I don’t think the LLM is gonna do that great of a job with it for this reason, but still worth giving a shot. ChatGPT is a well trained coding chimp. You realistically could get a well trained chimp to start off a lot of projects and have people finish it. The fact that it can correct itself after you explain how it’s wrong is very powerful as well.
LLM isn’t gonna be useful for converting a single program from COBOL to Java, it is gonna be useful for converting many programs from COBOL to Java. I bet IBM is trying this on their own shit first before they try to sell it to customers, because language conversion software would be a HUGE but very boom based money.
As I stated on a different comment in this thread, I worded my comment poorly. Why I think this is relevant however that, at least in this case, if an LLM get code which is significantly different from what its trained with, it can make wildly incorrect guesses. While here its because of a language with a… unique syntax, I think this could also be the case for code with a lot of technical debt or weird design decisions.
Yeah, I don’t think this will be as good as we want. The amount of technical debt I’d expect in these big programs would be off the charts. It would take a full team of people just to feed in corrections, and they would need to both know COBOL and be willing to kill all the COBOL jobs to do it. It’s a tough ask
I’m still optimistic though because it’s IBM and converting between languages is a billion dollar question. I don’t think IBM would do a truly irresponsible deployment of such big corporate changes. I’d expect IBM to do a LOT of testing before sending anything out that would actually change the world, such as banking software. But in could be wrong.
IBM hawks new conversion tools all the time. None of them are amazing sliver bullets, all of them require humans to comb over the resulting output. And every single one I’ve ever used chokes on any weird case.
From the RPG fixed form to free form, DDS to DDL conversion, and so on all of them are usually more trouble to use than to not use.
IBM does this kind of stuff all the time. And for some folks it’ll work some of the times. But at this point, I just skip any WS tool they put out and have a snippet on RDi and RDz that does all the required plugging away to call web services from the COBOL module.
