Framing the Fermi Paradox: Explanations, Detectability, and SETI Strategy

To the point

Whether extraterrestrials exist and can be detected is debated: Hart argues ET may not exist, Brin and Ashkenazi argue it exists but is hard to detect, and all optimistic views rely on assumptions that, if true, lower the chance of future contact, while the real likelihood depends on which explanation you favor and how adaptable your search strategy is, because design choices, technology, and even detecting signals without direct signaling can complicate predictions and keep the question unsettled and framed by how we approach the search.
