It's perfectly acceptable to be so-so in C++ for some companies and some projects...

And it's a good strategy to prioritize AI skills, learn cutting-edge elements of it; have fun, go beyond just 2D Object Detection, but dive in 3D Tracking... go beyond single-task learning, but embrace HydraNets, etc...

But some other skills can't go, and I think ROS (Robotic OS) is one of them. ​Spend a minute looking at self-driving car engineer job offers, and you will see ROS listed most of the time. When you want to do Physical AI work with real cars, real robots, ROS will be most of the time mandatory — you can't really go around it.
