Modern C++ is mostly syntactic sugar over older C++. If you manage to walk the happy path entirely within said syntax the code looks quite pretty. Lots of the language design is about having a nicer way to express common ideas. If you stray from the happy path, the demons come for you. Or if your use case isn't met by the existing sugar. Or if you have a dependency which was written a couple of years ago that you need to reach into. And naturally the project started from scratch today, only using the very nicest C++ features, will be legacy code written wrong in three or six years from now as the language moves on. I wouldn't want to start a new project in C++ today but I'm not totally confident there's a better choice available.
