Scala isn't as hot as it used to be. I think the rough Scala 2->3 transition, coupled with improvements in the base Java language, emergence of Kotlin + Android support, and popularity of Python in data science and data pipelines (lets just do everything in one language became popular) kind of made Scala not quite as popular as it could have been. Plus the long compile times are a pain. However it seems to have a rea…
You got it. Scala had a shot being an early mover in the JVM functional programming space, but they really shot themselves in the foot with their version transition problems and tooling issues you allude to. Java is probably "good enough" for most shops now, and if you are not bound to the JVM I really don't understand why you would go with Scala today.

Scala's metaprogramming abilities coupled to a powerful type system are still unmatched. Among mainstream languages, only TypeScript gets somewhat close. For your typical service oriented architecture, libraries such as Tapir or ZIO HTTP are pretty nice. I haven't found anything as pleasant in other languages.
That said if an LLM can write 95% of your code today, this point is a bit moot, sadly.
