The the unseen ones are mostly the harmless ones. The grabby (basically the "expansionist Dyson sphere builders") are the ones we should be on the lookout for.

We don't see aliens because if there were aliens to be seen they would be in our place. (Because the hard-steps model parametrized by habitable zone time-frames limited by the lifecycle of stars gives a distribution of emergence of intelligent life. And if just a few of those start expanding, they'll soon cover enormous volumes, taking away the possibility for later emergence of intelligent life.)
