If they're children then their parents, i.e. creators, are responsible.
We aren't, and intelligence isn't the question, actual agency (in the psychological sense) is. If you install some fancy model but don't give it anything to do, it won't do anything. If you put a human in an empty house somewhere, they will start exploring their options. And mind you, we're not purely driven by survival either; neither art nor culture would exist if that were the case.
