I see no issues using Scala in a simple context. When you buy more equipment for your entertainment room you do not turn on all the devices at once, you use what you need. From that perspective, it is very possible to right clean, maintainable, succinct, performant code in Scala with classes, case classes, pattern matching, immutable data structures and the stackable trait pattern. Scala 101 as far as I can tell is fairly obvious if you have done a lot of Java programming - you know where the pain points are and how Scala can shorten or eliminate the problem. I think something which would serve the great majority of Java developers as a better Java. As a Scala newbie, I didn't find it hard to get there to understand how I can sunset my Java programming with Scala, and I'm having a hard time finding a reason to go back. The arguments against Scala (like yours) seem to often get lost in big ideas (being a lifelong musician myself Hickeys instrument talk was only marginally inspiring), whereas I'm looking at LOC and syntax and I really like what I see. I can do the same thing in Java, but with more effort. I think the only benefit Java enjoys right now is better tooling. It still might be the best choice for large teams due to way it shoehorns development styles (and I actually don't mind coding it in at all, its pretty nice), but for my personal projects, I'm definitely focusing on Scala right now.
