High level languages tend to hammer the allocator like a Piñata. C++ can improve code smell of C, but different languages have their own specific use-cases. The reason llvm and GC based languages is a problem in low-level real-time code is bewildering for many.

Java is unique in that it often ran a dual stack for byte code, and platform specific binary objects.

My advice often is to use high-level languages if you can get away with the convenience, and a low-level language with proper design patterns if you must.

Many programmers I've met shouldn't write C/C++, but mostly because they can't be trusted to use memory or thread safe code.
