Why still use C++?

So, why do people still use C++ if it is so complicated? Here is what I was thinking tonight. I was watching that lecture about the C++ Renaissance, but a lot of the code was so messy even for very basic stuff. Also, the libraries were very limited to just basic computational stuff. Then we look at things like Java or Lisp were the already given libraries can do things like GUI and concurrency (C++ took a long time to catch up). Everything is pretty safe and easy to code. I do not understand why so much of the industry still uses C++.

Python and Ruby (I don't know about Perl) are designed and implemented by people who don't have a clue about anything. Using the result of their cretinism as a way to benchmark success is stupid. Learn to troll, faggot.
