In my life, I've mostly dealt with people that speak English. I tried Latin in high school and Japanese in university, but I wouldn't say I learned a lot. This past year I've been working on Japanese (konichi wa) and French (Bonjour) on a regular basis, but I'm still fairly uni-lingual. At least compared to many of the people I've met in my travels that speak multiple languages. I'm mostly just trying to read a bit, and that's quite hard.

In my career, I haven't met many technologists that only know one programming language. Even the SQL professionals know a little C# or a scripting language. Quite a few people know a bit about many languages, and some are very competent. I used to think it would be good to master one language before moving on, but I find that trying different languages can give you an appreciation for others, or even an appreciation for your primary one. Comparing and contrasting code might even help you learn faster.
