SomeDude:
The problem is, the C++ community is unwilling to collaborate with anyone else and this attitude is encouraged by Stroustrup.
The C++ language has plenty of warts and unnecessary complexities, but to me the C++ community seems normal, like other languages communities. Usually such communities don't collaborate a lot with other ones (I have seen the Python community collaborate a little with the Julia community, but such collaborations seem the exception).
