There is no prescribed script about what our evolutionary value should be. We will be whatever we ourselves make of us. Unless something unexpected happens -more advanced aliens intervening with our specie for example- Our human instinct is to grow, explore, discover, compete, share as much as we can. AI should be seen as a tool to our goals. Not as an end by itself. There is of course the possibility that we may loose control to the AI. That is not our desired goal, but it could happen. In that case our future will not be our decision. We will be at the mercy of whatever the AI choose for us. That will depend on what kind of AI we built, and how the rampant AI chooses to modify itself. But we will strive to reach our human goals. Because that is the human nature.
