Game engines are one example, there isn't a robust-enough language other than C++ that has the ability to build some powerful abstractions while also giving you the tools to manage hardware more directly. Note that Unity uses C# as a scripting language, but under the hood the core engine is all in C++.

Under the hood some of that C++ code is now the C# subset used by the Burst compiler.
