Plus, R's performance limitations are not that big of a deal. In my experience, the bottle neck is just a couple of lines of code that can easily be replaced by some lines of Rcpp. Much easier than switching to a whole new language and ecosystem. I was really excited when Julia was new but the cost of switching is just never going to be worth it for me personally.
