Why use C++ in this day and age?

Recently, C++11 information was released. I do not really understand what is going on this time. Is Microsoft back to supporting C++ programmers? Why use C++ when writing in C# or Java or other languages can be so much faster, safe, and require less lines of codes? Yes, C++ can be faster in cases, but computers are getting a lot faster. Plus, the standard libraries of C++ are somewhat lacking.

C++ is going the way of C.
