Why we stay with C++

Garbage collection is still garbage.
Zero-overhead principle. Nothing included by default.
As fast as C. C++ + assembler remains the fastest and most productive code.
C++ is easy to learn. Even the most arcane meta-template and pointer syntax can groked in a day(not professionally, just enough to use it). 
Alternatives to C++: Ancient languages and academic languages without any practical advantage over C++.

Boehm-Demers-Weiser garbage collector.

I understand why programmers of a more fundamental approach scorn anything with a garbage collector, but I do fail to understand why they do not view improving the shortcomings of garbage collection as a programming challenge.
