whether humans become extinct or merely unnecessary
This is still certain doom. Nobody can decide for you what you decide yourself, so if humanity retains influence over the future, people would still need to decide what to do with it. Superintelligent AIs that can figure out what humanity would decide are no more substantially helping with those decisions than the laws of physics that carry out the movements of particles in human brains as they decide. If what AIs figure out about human decisions doesn’t follow those decisions, then what the AIs figure out is not a legitimate prediction/extrapolation. The only way to establish such predictions is for humans to carry out the decision making on their own, in some way, in some form.
Edit: I attempt to maybe clarify this point in a new post.
