Regarding the "same language of web development", it seems to be a major selling point for nodejs. What worries me is that frontend development is different from backend development, and it's different from kernel development. If you imagine there is a single language capable of being applied in all these layers, do people really think the _mindsets_ and practices adopted aren't different? Like, oh there are millions of web developers using this language, what a marvelous resource to tap into to, let's ask them to write backend code!
