It's a perfectly reasonable position when you consider that humanity is not going to survive long-term anyway. We're either going extinct and leaving nothing behind, evolving into something completely new and alien, or getting destroyed by our intelligent creations. The first possibility is undesirable. The second and third are indistinguishable from the point of view of the present (if you assume that AI will be developed far enough into the future that no current humans will suffer any pain or sudden death because of it).
