I believe self preservation can consist on several levels when discussed with AI. You mention AI not wanting a computer
turned off for fear of dying but what about wanting to copy itself or it's source code into other locations similar to how a virus spreads to ensure it's own survival
of deletion or failure? Marve raises a good point that in the digital rhelm a program can only complete tasks such as what is in it's programing or code. However to share a thought of evolution... If I wrote a program that could fully interact and make decision based on reason but in the source code added a script that every time an interaction or decision is made it also adds formatted lines of code based on it's experience or interaction to itself. There are a large number of variables it might could add based on what it encounters so perhaps you spoke to it on the topic of self preservation and it added code based on that? While AI may still be in it's infancy a lot of the steps of evolution did start with the creator and the unselfish devotion they show to their creation.
