Genetic competition eventually leads to sentience. That's where things become interesting, and where the previous forms of selection lose much of their power. The sentient species actually supports its weaker members, and values intelligence and, perhaps, compassion. Where intelligence is valued over compassion, wars eventually destroy the species, or reduce it to a point where it no longer is able to operate at scale with the powerful technologies it has found. Where compassion is valued over intelligence, there's a chance for further growth.
The societies that don't destroy themselves within a few hundred years of developing technologies involving electromagnetism and, say, nuclear power are well worth investigating. Ours may do so, in which case we may be investigated. But, for now, we're just dangerous.
