The source material for this does, we have the potential to become a grabby species. In particular though one of the strange things we can observe about the universe is how early we are, relative to how long we expect the universe to last. The grabby idea explains this puzzle pretty nicely by a selection effect: if the universe is going to be grabbed in the future (by us or others), then being early is the only time at all that we could find ourselves with our seemingly natural development history.
