Now if he said they had no such luck w/ Java/D/Rust, then perhaps I could understand your ultra defensive fanboi position.
But since the post was on topic of Go and we do have quite large Go infrastructure I just wanted to comment that Go is awesome. More people should know about the awesomeness and perhaps experience the same as we did.
Greybeards like myself already experimented "Go's awesomeness" in the form of Modula and Oberon derivatives in the early 90's.
Having said this, reducing the amount of C code in the world, by using memory safer languages is surely positive.
It's kind of like if I excitedly told my friend I'd run an eight minute mile, and she replied, "oh, so what? Lots of people can do that". Technically true, but unnecessary.
