I think the solution to Drake's paradox is simply that the power, reach and capability granted by science and technology to civilization raises so exponentially as a function of time that each civilization spends only a very brief amount of time, compared to the age of the galaxy or indeed the total life span of a civilization or technic specie, in the era when what it does and how it interact with the universe is detectable and recognizable to us.
If 1,000,000 technological civilizations had arisen throughout the history of the Milky Way at random times since ~9 billion years ago, when the first terrestrial planets have reached 2-3 billion years of age, and on average each civilization spends 100,000 years in the era when it interact with the universe in a way we can both detect and recognize, then on average, at any given time, there is only 10 civilization across the entire Milky Way that at a stage where it would be interacting with the universe in a manner we can both detect and recognize, despite the presence of many more of the total of 1,000,000 may have survived, prospered, and advanced to a capability, mode of interacting with the universe in modes we do not even have the basis to speculate.
