Well, it depends. I work on big clusters with lot of nodes. There you need to copy objects anyway. There is no shared state. I wouldn't like to use C there for example. In the language I work, objects are immutable and that makes it possible for a human to work with the cluster. And of course there is state, I know that every node is plenty full of state, but that is not the point and it is hidden from me. But if you writing device drivers, sure then it might not be ideal. Not all tools are useful for everything.
