The Fermi Paradox posits the premise of ANY artifact indicative of intelligent origins.
It doesn't have to be "self replicating drones." It could be inert bullets, arrow heads, sharp sticks, carefully arranged electromagnetic retro-reflectors.
Drones are a fad. The paradox doesn't require an alien implementation of drone technology, self replicating, autonomous, or what have you.
