Even if the language supports threads, that doesn't mean your application magically parallel. No language will give you free parallelism. Besides, most software you run was written by somebody else.
sure, that was my point about the problem being parallel or not. Of course the program make use of it and be multithreaded and cpu-bound or not. That was not the point. The OP talked about "developing in multi-threaded languages", which is 1) about new developments 2) about language being multithreaded or not. I believe we both say it shouldn't be a problem of language as in 2017.
