I feel like I am in a decently unique situation where I learned C++ throughout my preteens and teens, and got a job straight out of high school writing C++ for Unreal Engine applications. Most of the C++ jobs I see when I look are things that I just honestly do not want to do.
I don't really mind working with the language and wouldn't mind sticking with it. But I don't want to work on financial software, as I don't want to mess with people's money. I work in a game development context right now, and may for the foreseeable future, but I also know that I get paid less than others at my same level in a different context. That part hurts with the way inflation has been lately.
I think in the end, those factors drive me away from trying to further my career in C++ and instead move toward something that would at least pay the bills in the future. I didn't start with C++ and could pivot to other languages and stacks as needed. But it would be a bit painful to know that I put a lot of time into this language to just not use it and let the experience rot.
This also doesn't factor in the numerous jobs that I have seen postings for that I am not qualified for, according to their description. It's hard to become a Senior C++ Engineer when no one is hiring a Junior to Mid C++ Engineer. Probably part of the lack of "talent" is not wanting to invest in cultivating that talent.
