Well, his perspective is well known in all Go threads on HN and this is not only my opinion (look here [1]). He is repeating the same things[2] again[3] and again[4] and again. About M:N in Go, about why Go is worse because it doesn't have generational GC but when asked if he reached to Go team about that there is no response. If you look at his comments from last month you will see how much downplaying of Go is there + other languages. It seems that he only praise one language (ahem) in his comments.
