The criticism of Julia seems strange:

> But the big dealbreaker with Julia is it only complies on the fly. That means you can't just hand a compiled executable to someone. You must give them instructions to install Julia and all your dependencies first. That's no good for anything you want to ship like a desktop app or a game. You also don't want Julia on your server recompiling with every web request.

That's an issue with Python as well, but the Julia team is working on that.
