> Is any new code being written in C++? Apart from adding to existing C++ based projects like Chromium and maybe supporting legacy trading/financial services code bases what else is C++ being used for where all the modern new features would be helpful?
All Adobe products heavily use C++, Most Digital Audio Workstations heavily use C++, All 3D authoring software heavily use C++, Most new core Blender code is now C++ instead of C. Of Course, most game engines are C++ based as well. So this is just the consumer space.
There are domains where there is simply no alternative to C++ in terms of features and speed. Rust maybe, but I don't know enough about Rust to formulate an opinion. No need to say that C++ is absolutely here to stay.
