I fully expect us to find organic life on another planets sooner or later. However, I have my doubts about intelligent life. They could very well be less technologically sophisticated, in which case it might do more harm than good to interact with them (cf. Prime Directive).
Intelligent species tend to kill each other off. Note that we aren't the only hominids. Note what we are doing to the most intelligent of our cousins. Note what we did to the Neanderthals.
