There arent really a lot of jobs in c++. It might be pretty foundational but all the other languages are much more prevalent. like game engines are c++ but there are so many game engine writing jobs, much more game engine user jobs.
The job pool is smaller, I believe, but with high earnings potential (luck™), mostly in fields where performance is not a plus, is a must: games dev, robotics, HFT, system engineering, etc.
Basically all game engineers use C++, regardless of they are working on the engine or the game. It's wildly perf focused.
AAA/Unreal Engine games yes. But C# is the default for Unity. I'm shocked that Beat Saber – a flagship VR (very low-latency) game is in C#.
True that the game is written in C#, but I think Unity itself is written in C++.
