Next Generation of Scala
summary
Argument that Scala's next generation is libraries that are deeply principled and deeply pragmatic and that ZIO is a concrete example: ZIO exposes a ZIO[R,E,A] type that composes dependency and error types, supports declarative parallelism like forEachPar with parallelism 8 and 60s timeout, and guarantees automatic interruption and guaranteed resource release on failure. Examples contrast Akka and Spark (useful but not Scala‑specific) and Caliban which generates GraphQL from sealed traits to save engineering effort.
