<p><strong>Time Elapsed:</strong> 0 min.</p><p>Hi, my name is Hanno.I'm from the Netherlands, where I work at Info Support as an IT consultant.Besides doing consultancy work, I also teach a few courses.Now at Info Support we offer a wide range of courses, which exist mainly to get our junior colleagues up to speed with important concepts or products they'll need for their daily work.</p><p>One of the courses I teach is called 'Git for Developers'.It's a one-day course where we teach the students how to use Git as a developer (none of that GUI stuff of course; command-line For The Win!).Besides doing the practical stuff we also discuss the pros and cons of distributed version control systems and how they compare to the earlier VCS's, like CVS and Subversion.Now the other day a student came to me after attending the course and said: "Git is great and all that, but what is gonna be the next big thing?"</p><p>Which was a great question, because I couldn't really answer it.I was quite sure distributed version control systems like Git and Mercurial would be around for a while longer, so that's what I told him.And he replied: "Surely Git won't be around forever?!"Now I really hated the fact that I couldn't tell him more on the subject, so I decided to research the matter a bit further.And what started out as finding the answer to a simple question turned into giving a conference talk.Which is the one you're attending right now!</p><p>So, welcome to you all.I'm gonna assume that you are all more or less like the student I told you about.He just couldn't believe that everything in version control land would stay the same for a long period of time.And I hope you're also a little bit like me, when you also can't stand not being able to know the answer to a question.So, let's see if we can find the answer together, shall we?</p>
Now if I hear someone say that "Git will probably be around forever", it immediately reminds me of...

This idea has been valid in our industry for as long as I remember.If you think about it for just a second, you can come up with lots of examples.* Requirements change.* Priorities change.* Dependencies change.* Browser behaviours change.Agile was invented for a reason! To be able to cope with CHANGE.Because change is the only constant.---<!-- .slide: data-background="img/background/what-goes-up-must-come-down.jpg" --->[Photo credit: Quang Le](https://quotefancy.com/quote/833239/Isaac-Newton-What-goes-up-must-come-down) <!-- .element: class="attribution" -->note:And although Newton (*point*) probably talked about an apple here, his quote can be applied to a lot of things, including:* airplanes;* Bitcoin price;* browser market shares;* version control system market shares.---note:Speaking of browser market shares, when I was in college I did a talk on 'the browser wars'.The talk was actually quite similar to the one I'm doing right now.In this college talk I tried to predict what browser we would be using ten years later in time.The year was 2005.TODO: random feitje uit 2005, om het jaartal wat 'dramatischer' te kunnen onthullen.---note:This was actually one of the slides I used.This was fourteen years ago!TODO: add retro slide.---note:Now 'the browser wars' are a VERY good example of Newton's statement.Because in the beginning, there was the Mosaic text-based browser.Until it came down and the top browser became Netscape Navigator.Until it came down and the top browser became Microsoft Internet Explorer.Until it came down and the top browser became Mozilla Firefox.Until it came down and the top browser became Google Chrome.---## Key question: was I right?note:So, was I right with the browser prediction?What *was* the most popular browser in 2015?TODO: afmaken.---note:Now who in their right mind would dare to claim that Google Chrome will be around forever?I mean, it will probably be gone in ten years or so...By then it will have been replaced by a superior product.These replacements in the browser world have happened at least four times until now.And I can't think of a reason why it wouldn't happen for a fifth time.
---note:So let's see how these things have happened in the version control world!
