Depending on what you mean, this is currently not possible, and probably not ever possible, because as much as people like to call things "autonomous", these AIs are still ultimately being directed by humans to do things. Prompting an AI is on a different level of abstraction, like writing software in a HLL and using a compiler instead of keying in machine instructions on a hexpad, but IMHO it is still the work of a human.
