Of course, its entirely possible some alien species may not consider us intelligent or even sentient based upon their yardstick.
One interesting thing to really think about is how evolution has shaped our "intelligence". We often are worried about how an artificial AI may be fearful and attack us. But isn't fear simply something we evolved, an intelligent machine has no reason to fear death. It also has no reason to feel greed or anger or any of the feelings we've evolved in order to ensure our own survival. In fact a machine is more likely to have its code copied and survive if it doesn't feel these things. Now humor, joy, love, etc we may want to program in.
