Maybe we misunderstood us here a bit :-) I didn't mean that your C++ skills are decaying when you switch to automotive industry but before that you we're a C++ database developer. My thought was that instead of learning a particular programming language, become an expert in e.g. database systems. Maybe I can give you some personal information about stability of C++. Answer: in my opinion it depends on the industry. We are writing software in C++ for machines which will be used for the next 20 years. In our case, knowing C++ very well is a plus because our systems have to live long. For example some time ago we needed a software developer who has knowledge in C and assembly for the C51 microcontroller architecture for some old human machine interface. Nevertheless we're evaluating Rust for new projects. As you can see in my industry C++ knowledge is very stable but be prepared to learn a new language like Rust.
