I don't think anybody is denying that C++ was (and is) unusually useful, simply by virtue of being the only serious game in town when you need that whole "don't pay for what you don't use" thing, and general performance stemming from that. And devising a better replacement that retains that feature is hard, which is why C++ had so much time to entrench.

But it doesn't mean that we can't do it better these days.
