True, but I expect you to know which two or three /distinct/ tools you can work with effectively, and which situations they are most suitable for.
Not only that, but knowing multiple languages has a multiplicative effect, massively expanding how you think of programming in all the languages you know, even the stable standbys like C#.
At some point, you have to sit down and do the work with the tools you have if you want to get anything done. If I were to get serious about programming, I would use C# or Go because I found them the most accessible after trying lots of languages. There's nothing wrong with finding a niche.
