By using humor, I think Apple is attempting to avoid previous failures in the advertising space where consumers recoiled from the unsavoriness of using an AI to replace a genuinely important interaction. In that sense it's kind of a clever way of alluding to consumers' potential use cases without taking on the commitment of standing behind those use cases, and leaving consumers ethically on the hook for their decisions to use these tools interpersonally.

On the other side though, it definitely portrays the AI user as a sort of slacker, which is an interesting way to advertise a tentpole feature.
