In terms of language design, it seems like swift and julia are the most forward looking. I personally don't think swift will ever escape the Mac ecosystem, just like Objective-C never did, but something with the same DNA will. In the same way that Objective-C and Ruby both implement the philosophy of Smalltalk, I think that philosophy has yet to be fleshed out in a simple syntax that is natively jit'ed/compiled. The same goes for julia as an answer to R/pandas.
