/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)

I'm just going to give my opinion on C/C++ They were good language 20 years ago, but they're outdated and we really need a replacement low level language
