I'm kind of interested in learning a language like go or rust, etc... But I'm not sure. I'm having a hard time really "getting" what they are used for? What do you guys recommend?

@molaram Yeah that's my understanding, that they are really useful for a narrow field of applications and for everything else they are kind of sucky

I'm learning Go at the moment, and although languages usually shine in small areas, there's nothing stopping you spreading them out of the applicable markets per se.

Php is known for web, yet makes an alternative to bash for cli tools

Java, desktop applications / web, yet became the norm for android apps and some automation suites,

Javascript, well I don't understand that one either, everyone seems to want to use it for everything under the sun.

Learn a language, and use it where you see it will fit or make your life easier where another language fails.

There's no "law" to say a single project must only use 1 language.

Learning go too, a lot nicer for generating certificates than c# but definitely not the tool for everything

I know what you mean!! Some of them you can't just charge right into because applying the knowledge is the only way to keep your skills sharp. I just learn shit as needed now, because once you are comfortable with several languages the rest pretty much comes to you quick enough where you can get your problems solved. From my understanding, Go is a pretty powerful backend language that scales up well to the enterprise level.
