You can write object-oriented code in C too (e.g. gtk, glib etc). It just involves much more boilerplate, and it doesn't offer the same amount of built-in safety guarantees.

So I know enough Modern C++ to use it, but why would I when there are far better alternatives?

Because those alternatives, while better at syntax + semantics part, are still quite immature at IDE + libraries + eco-system part.

For example, try to use Rust to implement a UWP component callable from .NET, interacting with the Visual Layer, while using mixed mode language debugging inside Visual Studio.

those alternatives don't always offer what C++ has - for instance template<int I> is damn useful in many cases and not many languages have that
