I thought the Fermi Paradox suggested otherwise. Well, it suggests if life is common then some other civilization should have easily covered then entire milky way in slow self replicating drones long ago.
That fact that we dont find drones suggests one of only a few things
* life is rare
* we're first
* they all kill themselves before they get the drones built
