The Fermi paradox isn't a paradox, it's a strong constraint that models of ET life have to conform to. In particular, models with billions of ET civilizations in the galaxy appear to require strong (and I suggest implausible) assumptions about the unlikelihood of interstellar colonization. It's also an antidote to baseless presumptions that ETs (or even life of any kind) must be common outside our solar system.
