For me. Code expressiveness and Simplicity. If you can just send the computation around your basically don't need the entire message/protocol boilerplate in your execution code. For example, think of a game engine that allows to write code with loops and calling function that may wait for an event or a rule to be true. Imagine that your game can be paused stored in case of a connection lost, synced between different server or both at a server and at a client for fast response. Now without this language feature your basic game logic code gets, you can just have a wait statement inside a loop etc., How will you return to the same place on resume? You need more code, storing the entire execution state.. on every condition or a loop you either need to store something or have code that looks like a state machine etc., With this feature you don't need special design pattern, just write it, and the mess is in the language level.
