Hmm...I wish they had taken a bit more time to dig into the situation with Julia than simply to note it moved from position 51 to 52 on the ranking (is that even a significant shift?). Having just come from giving a presentation at this year's JuliaCon, I am more optimistic about Julia's future than at any point in the past. I think what we're seeing here is that Julia is making a concerted push toward v1.0. It was announced at JuliaCon 2016 that they are targeting JuliaCon 2017 for the v1.0 release. It should be expected, then, that the break-neck pace of innovation has taken a back seat to a focus on stability, but based on what is already on the roadmap for Julia v2.0, I don't see Julia moving anywhere but up.
(Also, I think the comparison to CoffeeScript is rather unfortunate. In my mind, CoffeeScript was primarily addressing shortcomings in JS that JS has, since, done quite a bit to rectify. Julia is not trying to be a better "X", so there's no "X" to steal away its momentum.)
