This is completely false. C++11 introduced a lot of new paradigms, and that's it. That shift was for the better, and I haven't met a single person who can honestly say that the changes they made turned it into a worse language. Quite the opposite: it's more expressive, readable, and easier to use.
My comment wasn't meant to disparage C++, I'm not saying it's not improving, I'm just pointing out that it's a massively complex language and that it's still evolving in major ways so there's stuff to talk about. C hasn't really introduced significant "new paradigms" in a long while.
