Agreed, I feel like most languages have converged into some kind of variant of C#. Even JS, if you count Typescript.

For multithreading, I would take functional over imperative any day though. The multithreaded code I write in Java ends up looking like functional code by way of chaining futures, but it is still hindered by the use of shared memory and synchronization (or lack thereof).

I enjoy C++, and the additions in C++ 11 and 14 are mostly good ones. But they don't do anything to make the language more approachable IMO.
