Go is a nice language for some use-cases, but a bit too light on abstractions for my needs. When I tried Kotlin a couple years ago, it seemed to be marginally behind Swift in terms of the power of the type system and some of the cool things you can do in Swift, and I'm not wild about targeting JVM, but I understand that situation has been evolving so maybe I should give it a second look at some point.
