Just kidding, there are many cool things that are in the works, including Go-style multithreading and effortless automatic differentiation of arbitrary code, allowing you to "machine learn" any algorithm without a complex framework.
But that's all stuff that's not even available in most languages—now is a great time to start using Julia:
1. The latest stable release is 1.1—code you write now will keep working on all 1.x releases
2. There's excellent editor and IDE support for Julia in pretty much every imaginable configuration
3. There's a solid debugger with interfaces from the terminal and IDEs (and I'm sure soon there will be many more)
