At a high level it might seem like that, but there's a big difference between "fast" and "realtime". We need to go fast, but the main problem the language needs to solve for us is to break the work down into a steady, realtime stream. Overall throughput is Julia's strong point, but that's not the same thing at all.
I would argue that Julia's strong point is generating specialized code, and facilitating generic programming. Throughput is definitely the driver, but I think several aspects of Julia's design could benefit real-time programming as well.
Currently, there are many blockers to using Julia in real-time application, such as dynamic memory allocation and lack of thread safety. But I find it promising that a subset of Julia could be used for real-time programming.
