The C++ (and many other languages) model of threads and locks have clearly proven overly complex and bug prone. It's incredibly easy to write software with race conditions and incredibly difficult to debug. The best advance in recent years, is recognizing that most latency is due to network access, and using single-threaded, but asynchronous models like in javascript. It definitely does not remove race conditions, but makes them much easier to understand and debug.
