I guess it's reasonable to be hopeful as a Java developer nowadays.

Modern Java communities are slowly adopting the common FP practice "making illegal states unrepresentable" and call it "data oriented programming". Which is nice for those of us who actively use ADT. I no longer need to repeatedly explain "what is Option<?>?" or "why ADT?" whenever I use them; I could just point them to those new resources.

Hopefully, this shift will steer the Java community toward a saner direction than the current cargo cult which believed mutable C-struct (under guise of "anemic domain model") + Garbage Collector was OOP.
