My favorite aspect of Dark Forest is that simply coming up with the concept also provides a resolution to the Fermi Paradox.

It isn't a good resolution, because it assumes all intelligent species in the universe must think and act according to the same rationale. But the one example of an intelligent species we're aware of (humanity) doesn't think and act this way - we've been blindly sending signals and probes out for decades now, and anyone observing our planet would probably notice obvious tech signatures.
