Reading this post it seems that Julia is the silver bullet for every programming problems (or at least the ones addressable in python). I guess it's not. It is just another (very useful, admittedly) tool for the job. I really can't stand when every new language or framework or technology or whatever tries to be THE silver bullet. How long it will be before we learn that such a thing doesn't exist and we are always going to learn new tools to solve problems in a hopefully more efficient way? Maybe in the future we'll have such a thing, but I bet my 2 pennies that it won't be either Julia or any of the existing languages.

Edit: speaking specifically about the language I think that it's a very good effort and it can be only a good thing for the current languages ecosystem, even if I don't appreciate some of its idiosyncrasies.
