While it's true that node can handle CPU intense tasks with WebWorkers or some other clustering there are also memory concerns. Node can doesn't mean it should with the exception of keeping your stack simpler (a single language). But that's a compromise to achieve a different goal. I personally like Go more these days because it doesn't have these problems, it's very easy to do concurrency, and it's memory overhead is much lower. This in contrast to my other favorite option, python, which is a nicer language imo, but it's concurrency story is worse and memory overhead is about on par (varying from case to case, but my point being they're both much more than Go).
