I wasn't on board with this analysis - "Zehr assumes that the Predators would have evolved to be less physically impressive and more reliant on their tech. If the Predators have... maintained a constant state of strife, then they've been failing as a species for a long time."

Another explanation could be that the decision to maintain physical strife, whether it was made consciously or not, could be the thing that has rescued their gene pool from wussification by their reliance on tech.

Apart from that, I wonder if this article's analyst would draw the same conclusion about a subculture that values suicide bombing?
