Great post above by PolymathGuru.
It's been over 10 years since I used C++, but because I've coded in C++ before I can easily pick up languages like C#, Java, Javascript, etc.
Also, Swift is the future for apps and gaming in iOS / OS X. Apple is wanting to replace Objective-C with Swift, though that will take a long while. I don't like Objective-C and I find Swift to be much cleaner, similar to C++ and it's derivative languages (except there's no need to manage memory or mess with hardware, etc).
