I'm guessing the best predictor of whether Julia will be the "one language to rule them all", is the difficulty of writing macros in it. If they somehow figured out a way to make writing lisp-like macros in a language with infix notation easy, Julia will easily become the next big thing. Otherwise I would have to say that the trade offs between syntax and macros would make lisp a better choice (see pg's argument for lisp macros[1]). For someone who has used both Julia and lisp macros, how do they compare? [1] http://www.paulgraham.com/avg.html http://www.paulgraham.com/avg.html
