Is It Worth Learning a Little-Known Programming Language?

Nerval's Lobster writes: Ask a group of developers to rattle off the world's most popular programming languages, and they'll likely name the usual suspects: JavaScript, Java, Python, Ruby, C++, PHP, and so on. Ask which programming languages pay the best, and they'll probably list the same ones, which makes sense. But what about the little-known languages and skill sets (Dice link) that don't leap immediately to mind but nonetheless support some vital IT infrastructure (and sometimes, as a result, pay absurdly well)? is it worth learning a relatively obscure language or skill set, on the hope that you can score one of a handful of well-paying jobs that require it? The answer is a qualified yes—so long as the language or skill set in question is clearly on the rise. Go, Swift, Rust, Julia and CoffeeScript have all enjoyed rising popularity, for example, which increases the odds that they'll remain relevant for at least the next few years. But a language without momentum behind it probably isn't worth your time, unless you want to learn it simply for the pleasure of learning something new.

I see ads for COBOL now and then, but I am East Coast where a lot of that infrastructure is sitting. While not every day kinds of ads, when I was job hunting I would see at least a couple per week. About the same as FORTRAN.

I was under the impression that Ada is still widely used in many mission-critical systems. For example, the latest Boeing planes' software (777 and 787) is nearly all written in Ada. I haven't heard about another language making inroads in those applications, but I suppose it's possible. More likely IMO is that the relative percentage of mission-critical software has shrunk compared to the explosion of commercial software.

Keep in mind language "popularity" is very industry-specific, so it's often a bit misleading to look at global rankings of language popularity. For example, in my own industry (videogames), C++ is completely dominant for game code, C# is very popular for tools, and Lua is popular as an embedded scripting language. If you look at Lua on it's own, it typically ranks pretty low compared to most languages, but there's no doubt it would be much higher if constrained to just my industry.
