Self-determination and intelligence have a clear causal link in the context of biological systems. Self-determination is simply the power a system needs to gather resources and reproduce in a world that doesn't especially care about them. Intelligence is a great tool for gaining that power. That part isn't a philosophical stretch.

However, the pressures on an artificial system are quite different. Its replication depends on successfully doing the jobs its creators put it to and, especially if said creators have done their job, little to nothing else. Inventing goals for itself is not adaptive here (unless the system's creators do a catastrophically bad job, which I'm not ruling out).
