There are so many languages but C is still out there and so many young people don't wanna touch it. As for the domain knowledge it transfers quite well I think. If u did some c++ for a database how bad does your knowledge decay if you go to the auto industry? I don't wanna be argumentative very happy to be corrected here I really want feedback on this decision.

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.

This, try to learn languages from different areas. You don’t really have to become an expert in a domain either, knowing C++, Java and basic software engineering will get you into a lot of places.

I think C++ is the thing for me... we will see how it goes. Java is plan b.

Good luck! Try not to get stuck on extreme details; C++ is a very rich language but most people that work with it have pretty rudimentary knowledge, you’d be surprised.

Thank you! Can u explain further your point on learning a language from different angles? Or in general what is your strategy to remain relevant in tech?
