About a decade ago, some Scala library authors thinking that "everything is better as a DSL" gave Scala a reputation for being a hieroglyphics soup, but that cannot be farther from the truth today. It's a really nice language to learn and to use, and the only one in my experience that I would want to take with me to scale from a quick dozen-liner script bash-style to a highly concurrent, highly available server application, from native to jvm to JS.
And the foothold in academics has some practical perks, too, like a sound type system (DOT calculus), compatibility guarantees at a theoretical level (TASTy), and what's cooking in the area of capture checking might be a general solution to many of the industry's biggest challenges (e.g. colorless asynchronous programming, safe errors, safe resource management, ... Think of Rust's borrow checker as a special case of this, and the consequences for scala-native as a systems programming platform).
