> I sincerely believe (as a computational scientist) that a combination of a high-level language for real-time interactive exploration and prototyping with a fast language like C for doing the actual gruntwork, is the best.

Converting to C can take a LOT of time, and is an order of magnitude less enjoyable than Julia. What about maintaining the code, making improvements, integrating with other code? And what if the prototyping needs too be fast too? It can become a massive pain in the ass. Why should I undergo that if I can just use Julia?

> Attempts to combine the best of C (speed) with the best of scripting languages (easy to do things fast without having to pay attention to what you are doing) in my opinion end up merely joining the worst of both worlds rather than the best of both worlds.

I've used both Julia and C and I think it's the exact opposite, it combines the best of both worlds.
