> better stick to js/python/java/C#/C++ like everyone else I would change Java to Kotlin here, since Kotlin has a 1:1 interop with Java while having goodies like null safety, type inference and functional programming without the academicism of Scala (and its slow compilation time). If you also account for the smooth learning, Kotlin is probably the safest bet from these 9 mentioned. A lot of businesses with Java codebases are already messing with it (and not only for Android).
