why is this ? i have worked on kotlin in the android ecosystem. But something like kotlin with spring is no better than java right ? you still have to deal with all the controllers, etc. on reddit, one of the arguments was interesting - the biggest value of kotlin in backend is using var/val instead of types and making everything public (instead of getters/setters). would that be correct ? Lombok doesnt fix this ?
