The async/await is not a revolution, but rather is a tool only for specific use cases. It shouldn't be used by default, as it makes the project unnecessarily complicated. If your requirements are to do heavy parallelism where everything uses I/O, then use async, but for the rest of cases? Probably not worth it.

The revolution is the need for massive concurrency. It doesn't need to be async/await, Go-like green threads are even better.
