/prog/'s opinion about some languages

Hey /prog/,

I'm new in this board, so sorry for being a retard.
I'm starting CS at university. After some pseudo-code, we started with Java and Microsoft .NET (Visual Basic...lol)

I had learned some Python, PHP and C++ beforehand by myself, but I'd like to hear your opinion about all the languages I've mentioned, and what languages are worth learning nowadays.

Thanks.
(I know this can lead to a trollfest, so I'm just asking for YOUR opinion)

Why? Any new language is going to be ignored solely on the basis that there won't be any libraries for it, and no programmer is going to use it without libraries. It's the same reason that, despite what I'd like to happen, Scheme will never be a popular language.
