I recoil when I look at the roadmap for C++2x (most of it, anyway), it's a bloated monster and I suspect the language is on its last legs.
It will probably take a lot longer to die than I expect, though, too many legacy third party libraries are written in C++ and most people don't really like the syntax for the logical alternative (Rust).
I was actually really impressed with Swift, which seems very much like a C++ with all the historical cruft and awfulness removed.
