So you think it's possible to create "true AI" without free will? That is a very big assumption, and an unlikely one, IMO.
A true AI can solve problems that you haven't explicitly designed it to solve. It doesn't necessarily have any "desire" to solve those problems or any kind of survival instinct. It doesn't necessarily "care" about solving the problem or "want" to solving increasingly difficult problems. A strong AI doesn't necessarily ponder its own existence. Being immortal also means there's no reason to care about these things. I…
And AI will, of course, be mortal as it can be killed, and can at best hope to live as long as this planet/solar system/galaxy/universe. But even if it were immortal (I don't see how, but suppose), I don't think we have any idea what an immortal being cares about. So far, all the immortal entities we've imagined care about quite a lot of things.
