COBOL’s been around for 60 years—and isn’t going anywhere anytime soon. We maintain billions of lines of classic code for mainframes. But we’re also building new infrastructures for the cloud in languages like Go.</p> <p>COBOL was a giant leap for computers to make industries more efficient. Chris Short describes how learning COBOL was seen as a safe long-term bet. Sixty years later, there are billions of lines of COBOL code that can’t easily be replaced—and few specialists who know the language. Ritika Trikha explains that something must change: Either more people must learn COBOL, or the industries that rely on it have to update their codebase. Both choices are difficult. But the future isn’t being written in COBOL. Today’s IT infrastructure is built in the cloud—and a lot of it is written in Go. Carmen Hernández Andoh shares how Go’s designers wanted a language more suited for the cloud. And Kelsey Hightower points out that languages are typically hyper-focused for one task. But they’re increasingly open and flexible.</p> </div> </div> </div> <div id="transcript-tray" class="tab-pane fade"> <div class="row"> <div class="col-12"> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>00:00</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>When the New York City subway first started running in 1904, it was a marvel of the modern age. But ... what happens when today's commuter depends on infrastructure that was designed more than a century ago? Trains are packed and often late. Two billion subway rides take place each year in New York, and nobody's marveling anymore.

Today we also have IT infrastructure, server farms humming in isolated fields, fiber optic cables spanning oceans, and software infrastructure, too. Like legacy operation system, or shell scripts that nobody dares to replace. When all that IT infrastructure gets old and creaky, we can't see it for ourselves. And yet, the infrastructure that makes today's development work possible is aging, just like an old subway track. And that can mess with our modern lives. Massive new challenges emerge as today's command line heroes work to make sure we're not being boxed in by the past. </p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>02:02</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>This is episode 5 of our season-long journey into the world of programming languages.

I personally think there's going to be a day where COBOL is actually in again. Really, what's going to happen when all of the developers with COBOL knowledge retire, and no new younger generations of developers are learning COBOL? Something has to give, right?

But what happens in a distributed system, and in a cloud, is that you have problems of concurrent messaging between distributed systems. You need to make sure that you have no problems with asynchronicity. Go is a programming language that is asynchronous by default. Basically this means that every operation you perform, like sending all these different messages to another in the system, it's done without waiting for the other system to respond back to you. So it can handle multiple messages at any given time.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>14:28</strong> - <em>Carmen Andoh</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>And that said, cloud computing is distributed. And so Go was developed to address this exact need. Go became, early on, one of the standard ways of doing this kind of distributed computing. And that's why I think that it picked up a lot of the developer mindshare immediately. Go absolutely is the language of cloud infrastructure, both in its design, but also in the ecosystem of all the cloud infrastructure tooling, and building blocks that have sprung up in the last decade.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>15:06</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Soon, major applications like Kubernetes were being written in Go.

Sounds great. And Go’s designers tend to create languages that last for a good half century. Also great. But my question is, what will that really mean 50 years from now when Go is more like COBOL? What will it mean when the world is teeming with legacy Go code that only older developers understand? Are we going to be prepared for a time when today's cloud infrastructure is aging? Are we learning lessons from COBOL and the world of mainframe that could help us design a better future for Go and the cloud?</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>16:40</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Luckily, I found exactly the right person to ask all these questions.

I was curious whether one day we're going to end up with another aging group of programmers with these wizard-like skills around Go, the same way we have a shortage of COBOL wizards today.

But if you think about some of the new challenges today, things like dealing with the internet, the network, you've got multiple users, hundreds of thousands of concurrent users, different collections of machines and architecture types. So given those new use cases, typically you want to have a new language. For example, JavaScript is for the web, you don't want to retrofit COBOL so that we can start doing web programming with it. So we have hundreds of languages that are out and pretty well established today, and they're all kind of hyper-focused on their sweet spots.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>18:15</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>So in that case then, do we need to actively push people towards COBOL?

So you've invested 10, 20 years in COBOL, and there is no one actively thinking about learning some new COBOL. Or you don't come out of college just like, "I'm going to double-down..."</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>18:45</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Right.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>18:46</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>"...on this language that's older than my parents." So in that world, you have to ask yourself, what is the risk of continuing on with COBOL? Is it still relevant going forward? I think it is still relevant for certain types of workloads, but we have to ask ourselves a question, is it time to progress? Is it time to evolve a little bit? So if you still have billions of lines of COBOL, you're in the situation where you're going to have to try to find all the COBOL talent that's remaining and bring them in house, but maybe we start to think about what can other languages learn from COBOL, and incorporate some of that functionality and libraries into other languages.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>19:26</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Life after COBOL, that would be an enormous infrastructure project all on its own.

A lot of cloud providers typically bundle up collections of technology so you have your choice of programming language, you have your choice of programming paradigm, whether you want to event-driven, or it's all web services based on [HTTP]. So what that means is you get to choose what you want to program in, and just kind of focus on what gets solved.

But we still want that ease of use of here's my job, you run it for me, tell me when it's done.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>21:24</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Absolutely. Do you see what's happening, or what's happened to COBOL, happening to any of today's languages? Like for example, Go, do you see us struggling to maintain Go and getting folks who want to write Go in 30 years?</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>21:38</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>I think all languages can suffer that fate, right? So if you think about it, Python's been around for a very long time. I think it's, what, close to 20 years if not more. So I think what happens ... and Python's had a resurgence in its usage, right, it's kind of the foundation of language for machine learning.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>21:53</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Yep.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>21:54</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>For libraries like Tensorflow. So if we use just time alone, I think that's probably not the right way to look at it. It's like how relevant is that community? How relevant is that language willing to adapt? And I think what Python did really, really well, it ... that community saw the ability to make other languages easier to use. For example, Tensorflow's a lot of C++ underneath it, so programming in such a language is probably not as user friendly as something like Python. And you could take Python and use it to generate some of the stuff that people are using for, example, Tensorflow. So now that machine learning is hot, people have brung Python into that new space, so guess what? Python continues to be relevant, and will be relevant for some time to come. And the same thing's going to be true for Go. If Go can continue to be relevant, right, it's like at the foundation of many of our infrastructure tools, many of the cloud libraries, it too will remain relevant. So I think it's all about those communities ensuring that they have a place in the future, and when the future shows up, making sure that they have a story there.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>22:58</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>Yeah. So how do we future-proof our languages? Meaning, how do we intentionally design a language to make it last, and make it relevant 20, 30 years from now?</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>23:10</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>The people that use the language, so this is something that's really unique I think, in the open source space. Now that we've moved away from commercial languages, right, languages used to come from Microsoft, or Sun Microsystems in the case of Java™, and at that point everyone relied on the vendor to do all the heavy lifting about what the language would be able to do, any new improvements in the run time. Now what we see with things like Go, Node.js, Ruby, all of these are community backed and focused runtimes and languages. So anyone can add new libraries, right? There was a new [HTTP] spec, right, [HTTP/2] came out a few years ago and each of the respective communities just had contributors add those particular libraries, and now guess what? All of those languages are now compatible with the future of the ... kind of the web for the most part.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>24:01</strong> - <em>Kelsey Hightower</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>So I think it's really now that individuals have more control if they want their language to be relevant for new use cases by just contributing that functionality themselves. So we're not restricted to one or two companies. If the company goes out of business, then maybe the runtime dies with it. We don't have that problem as much anymore.</p> </div> </div> <div class="row"> <div class="col-12"> <div class="card mb-2"> <div class="card-body p-1 bg-white text-purple"> <p class="mb-0"><strong>24:23</strong> - <em>Saron Yitbarek</em></p> </div> </div> </div> </div> <div class="row"> <div class="col-12"> <p>We've said it on this podcast before.
