I used C++ for a good while (systems programming). I like it and still use it for some things. But when I started using Go, I used C++ less and less. Go was simple like C and almost as fast.
There is a time and a place for all languages, but if I could only have one, I'd probably pick C++. It can do almost anything in whatever programming style you prefer. It really is the most generic language I've ever used. That's both its strength and weakness.
Also, the fact that C++ is standardized (ISO) and not controlled by a company (Google, Microsoft, Apple) I feel it offers greater freedom. No vendor lock-in.
