I think an important takeaway here that many often ignore is that in language design, not having low-level control over something is sometimes just as important design tradeoff as having it.

From that it also follows that it may not be too fruitful to try to tackle every domain there is with a single language only.

(With that said, I absolutely love sync Rust, and Go is definitely not a good example of an elegantly designed language, I am talking in a more general way here)
