IBM Shares Crater 13% After Anthropic Says Claude Code Can Tackle COBOL Modernization (cnbc.com) 113

Posted by msmash from the how-about-that dept.
IBM shares plunged nearly 13% on Monday after Anthropic published a blog post arguing that its Claude Code tool could automate much of the complex analysis work involved in modernizing COBOL, the decades-old programming language that still underpins an estimated 95% of ATM transactions in the United States and runs on the kind of mainframe systems IBM has sold for generations.

Anthropic said the shrinking pool of developers who understand COBOL had long made modernization cost-prohibitive, and that AI could now flip that equation by mapping dependencies and documenting workflows across thousands of lines of legacy code. The sell-off deepened a rough 2026 for IBM, whose shares are now down more than 22% year to date.

        If it works, why replace it?

        That's a serious question. Valid answers may take the form of:
        -The new permits monetizable uses the old does not.
        -The old is unlikely to remain functional for lack of platform or vendor support.
        -Neither of the above apply; the solution is feature-complete and we have enough market clout to keep it sustainable.

        Like it or not, the last option applies to a lot of stuff. Not just software. The humble fastener for instance. Nails and screws are mature technologies. Adhesives not as mature, but ain't nobody seriously talking about framing houses with glue alone on account of nails and screws are a sunsetting technology.

They run VMs, not the other way around, and there isn't a platform out there that can provide the transaction throughput or uptime of a Z-series.

            As LostMyBeaver explained above, "The problem is that JCL, RPG, CICS, DB2 and all the surrounding infrastructure is very confusing." This would be the CSS, JSON, CGI, PHP, SSI, and other infrastructure that our imaginary web portal interacts with. Creating a static web page is fairly easy. Combining everything into a dynamic infrastructure takes time and multiple iterations.

            Same with the COBOL code. The programmers experimented and found solutions to all the edge cases, all the system calls to the OS, all the file locking and transaction logging that is required for audits, all the database calls, etc. that would be difficult to transcode onto a different OS and hardware.

            So finding replacement COBOL code might be something that AI can help with, but unless you build a virtual machine to replicate all the old system calls, then test your new code in C, Rust, Python, or the language of the day and then determine what OS and hardware you are targeting, you really don't have a replacement solution.

      Exactly there have been COBOL-to-C transpilers for years as well. The output is well usually a pretty brain dead conversion of COBOL to C in way that maps COBOL data divisions on C structs and unions in a way not human C programmer would think to do but none the less it is possible to start chopping up the resulting C-BOL into libraries you can link to other C code or call into from pick your favorite scripting languages FFI interface for C.

      There have been tools perfectly suitable for decomposing COBOL nests into understandable parts and subsequently rationalizing or rewriting in newer technology bits for decades.

      The issue is always the *risk*. COBOL doing control-break-logic batch processing in your mainframe environment can process basically unlimited quantities of records with extremely predictable memory high water marks, run-times, and failure modes. That is actually hard to deliver with newer tech, at least if you talking the transaction volumes of the largest international banks.

      If you can't trust a deterministic conversion of COBOL to C, how could you trust the outputs of some statistical model converting COBOL to pick your other language and its like much larger than C's standard library and run-time environment?

    There are three problems when dealing with legacy code.

    1. Figuring out what the code does.
    2. Figuring out what the code was supposed to do.
    3. Figuring out what the code actually should be doing.

    The three are often not the same. The code lies. The comments lie. The commit messages lie. The documentation lies. The managers lie. The users lie.

    By lie, I mean, what they tell you, regardless of what they believe to be the truth, is not reality.

    For example:

    Someone took a stab at writing some code in a modular fashion, or someone before you refactored it. There's a function - it says getXYZ, and it returns a value. Great! Then you dig deeper and discover that getXYZ sets several flags which are then used by the calls that come after getXYZ in the block you are looking at. You discover this only after shit starts breaking because you reordered several function calls during refactoring, none of which had the singular result of getXYZ as a dependency.

    An even more straightforward example of that would be discovering a bunch of shit broke when you looked at and found that nobody used the result of getXYZ, and refactored out what looked like dead code. Again, because getXYZ, despite the pattern, actually had side effects.

    At this point, now you have a problem. Is getXYZ actually supped to return a result that someone is supposed to use? Was that its original utility, and someone just jammed shit into it because it was faster than refactoring it into something else? Or was it even worse, and this was an incomplete refactor?

    Nobody knows! Nobody can tell you! The commit history doesn't go back that far, and even if it did, nobody actually leaves coherent, useful commit messages!

    And don't get me started on documentation and comments. Sometimes they can tell you how the system was supposed to behave at one point... but that's not how the system behaves now, and it isn't how all the users and managers believe the system is supposed to work because they've been using the current system for so long.

    "Fixing" the code to follow what was supposed to be the correct design can cause all sorts of problems with downstream processes that rely on the current broken behavior. I'm going to steal Uncle Bob's example of finally fixing a typo in a dropdown menu and causing a bunch of UI macro code that looked for that typo to fail...

    Often times modernization means essentially re-negotiating all the contracts and interfaces and process workflow with all the stakeholders to come up with a common understanding of what the code should be doing. That's like the best case scenario.

    The worst case scenario is they say - use the old code for requirements, make it work exactly like that. Well, if the old code is shitty and illogical, and you need the new code to interface 1:1 with everything that plugged into that... well, guess what? You're going to get an architecture that is going to replicate shitty and illogical 1:1. The actual code might be great, but the process will be just as hard to understand, and probably eventually just as head scratchingly difficult to modify and maintain.

    I wish our robot overlords the best of luck with this problem.

    COBOL isn't a legacy language. It's domain specific language that is designed for exactly what banks need: high precision math without floating point errors.

    Any Comp Sci student should be able to take what they learned and apply that to COBOL.

    What actually sets COBOL devs apart is their attention to detail and ability to do math.

    Even if backend banking code was written in TypeScript, they would still have to hire the best of the best to work on it. You can't have errors at that level.

  • They've been trying to kill cobol since the day it was created. Every single time they try to modernize it... more cobol is created.

  • Recently, I asked GitHub Copilot (using GPT 4-o) to upgrade a Vue.js 2.0 component to 3.0. It worked fine. So I asked it to upgrade some more components. Oops. Anything with any level of complexity, it made random additions and deletions to the functionality.

    Maybe Claude is better than GPT 4-o. But I doubt it's *that* much better.

  • When they say "made modernization cost-prohibitive", what it actually means is "it's not worth it to change". It all works. It works fine (demonstrably). It's not something that needs to be changed but costs too much to change, it's something stupid people WANT to change but can't justify it to shareholders.

    tackle (verb)
    1. To attempt (but not necessarily succeed at) a task.
    2. To knock down so as to impede forward progress.

    Either way, I'm sure Claude can tackle modernization of COBOL code.

    If there is inadequate training to understand the full semantics of COBOL as used, that enterprise is likely to fail. That universe is not as large as C or Python for training. The question then becomes whether the specifications for these languages are precise enough that correct translation can occur.

  • I can hardly think of anything IBM does that cannot be done better and/or cheaper by somebody else.

    I have worked for IBM, as a contractor, and there was a time when I was impressed with company. But now, I don't see much of a reason for IBM anything.
