C++ is fine. It's just nobody likes designing and writing lighter weight tests and simulations to keep local dev workflows productive. For things like AAA games and OS development, I'm not convinced simply picking another language solves the problem. At least not while keeping all the same benefits. C builds faster, sure, but it doesn't have the same feature set.
