If our notion of self-worth comes from the economic value we add, or if it comes our intellectual pretense (*cough*), AI may pose a serious challenge to our self-worth.
On the other hand no one takes up activities like taking care of children, teaching children, taking care of the elderly, coming back to farming leaving a well paying job, going into the forest as rangers because they love the forest, local temple priests who do the daily rituals even when no one shows up at the temple, classical musicians who practise daily and perform for even very small crowds - none of them do it because those activities pay well.
They will be unaffected by AI. Humanity may organize itself more towards such activity.
