> Mobile development Android NDK, Objective-C++, ... > desktop applications There are plenty of applications written in C++, from legacy code bases like MS Office to almost all content-creation tools ever, most applications whose abbreviations contain "computer aided", many libraries, and boatloads of applications. Like I said, C++ is used practically everywhere. Most applications developed on Qt are C++ (some Python). Qt itself has already a large user base. > data analysis From matlab to gnuplot, oscilloscope and spectrum analyser software, data analysis applications are frequently developed using C++. > machine learning On many repositories I can rather clearly see a broad pink bar, e.g. https://github.com/search?utf8=%E2%9C%93&q=topic%3Amachine-learning+&type=Repositories https://github.com/search?utf8=%E2%9C%93&q=topic%3Amachine-l... https://github.com/tensorflow/tensorflow https://github.com/tensorflow/tensorflow - If some proprietary application is not obviously written in .NET or Java, C++ is a safe bet.

  My problem with your line of argument in this whole subthread is that no matter how many examples people give you of important categories where C++ predominates, you've already decided that the sum total of all that is "niche".

    This subthread did in fact become and argument, and now it's a witch hunt that inspires nothing but deep hatred and loathing. Some comments have been helpful, and others have been shitty. I've only responded to the shitty ones. What I really wanted to know was what can I use C++ for as an individual developer. Maybe I should have been more explicit in my original question, but ultimately the answer is that there's nothing I can do with C++ that I couldn't do better with another language - short of joining a large dev team to build or maintain a large legacy codebase. However, I no longer care about my original question and am just as happy to see this community burn. So it goes.

      I'm interesting in your background: which languages do you use, and what kind of programs do you write? Perhaps it'll become clearer whether C++ is any use to you or not. From the discussion I've read in this thread so far, it seems like you're claiming "what's the point of the entire field of mechanical engineering" when you, personally, just want to drive a car (not build one), fly on a plane (not build one) and so on.

You've misunderstood. What I'm claiming is that there are very few tasks at hobby-project scale that C++ is ideally suited for. C++ is a language that's used at team-scale, and is no longer an approachable language for the individual. In other words, with Java you can build Android apps, with C# you can build Unity games, with Python / JavaScript / Whatever you can build web apps. What can the individual do with C++ they couldn't do easier faster or better with some other language? Maybe embedded systems - but C seems just as effective for that domain. Likewise for kernel development for obvious reasons. I actually want a reason to use C++, but "well you can work on Photoshop or high performance computing or HFT plumbing software" is not a helpful answer - both for me and anyone else hoping to pick up Cpp in their spare time.
