Or to take it a step further, whether it is inevitable that intelligent life will have both the capability and opportunity to make their presence known. Maybe some planets are full of superintelligent dolphin-like creatures that had their development stall because they didn't have the dexterity to manipulate tools to the extent that sapiens can. Or maybe there is intelligent life on a planet similar to Europa that never prioritized space exploration/communication because instead of an Earthlike atmosphere their planet is surrounded by miles of ice.
