As I mention in another thread, it is a matter of what kind of systems level work you mean, given its successful use in embedded platforms, namely military, office devices, manufacturing automation and IoT.

Kotlin and Scala have Sum types, and Rust still needs to catch up with Scala's type system.

The owners of Java only sue reimplementors that don't respect licenses, like Microsoft and Google.

None of other commercial third parties has had any issue with Java owners.

Naturally I am not advocating for you to use Java instead of Rust, rather that it also has its uses in system work, and it is a valid option in scenarios where having a GC enabled language isn't a problem.
