In such a scenario we're walking the line between life being very rare or nonexistant.
In fact, I don't mind the fact of us being alone: the more space for us to expand into until we run into someone else. However, history teaches us to be wary of anthropocentrism: this system almost certainly is not very special. Perhaps intelligence is as commond as stellar dirt.
