I've been programming in C++ for the past 15+ years, from some toy UI applications to things like a fully-featured software DSP for a telecom gateway. I don't want to discourage you, and I think everything I did during this time was a good experience and taught me a lot. If you feel that's important for you, go ahead. My point of view, which comes from my personal experience: even though Rust has some limitations, a number of areas for further development and a few rough edges for lower-level development, at this point in my career I don't want to touch C++ anymore unless I have no other choice. Modern C++ is much better but it is not a paradigm shift (safe by default), the same way "labelled goto" (ie, C) is better than "numbered goto" (ie, BASIC) but it is still not a while/for. You might reach a similar conclusion, or you might not. I just want to leave this here for you to reflect upon. Regarding material, it all depends on the platform and what you would want to use C++ for. There are many references here already, so my advice goes to focus on C++ concepts and techniques and not too much on specific libraries - since they can be unavailable or impractical for certain environments/platforms.
