Articulating concerns with Go is a legitimate (if, for this particular thread, unproductive) way to use HN. Writing comments like "Go is a toxic language" is not; it's morally indistinguishable from trolling.
The comment rooting this thread, suggesting the use of Go instead of C++, was also unproductive. I'm glad to be done with the C++ part of my career, but still happy to read about ambitious new libraries built in it. That upthread Go comment is the kind of tangent-driving chaff that made Slashdot unreadable. But this comment is even worse.
