Dear Dr. Loeb,

There is no gainsaying the fact that you are a brilliant astrophysicist, able to present compelling presentations on incredibly complex ideas in a lucid manner, readily accessible to lay readers.
But I wish you could relinquish your obsession with extraterrestrial (or extragalactic?) intelligent life, out there trying to make contact with us here on Earth. There’s zero evidence for this, so far, despite all our earnest efforts to find any hint of actual intentional information in the random signals across the electromagnetic spectrum we have studied so far.
Stuart Kauffman has an entirely plausible explanation for the uniqueness of human language in evolution, deriving from his extensive research into molecular biology and evolutionary patterns: he refers to this as the “adjacent possible,” which refers to the fact that every successful genetic mutation opens up a hitherto unimaginable array of new possibilities, in a fractal pattern of possibilities that proliferate exponentially and unpredictably in the next evolutionary pulse. The net result is that no two “runs” of evolution from a single eukaryotic cell will ever be identical. As a consequence, there is no reason to suspect that anything resembling human language (i.e. digital rather than analog communication) EVER could evolve anywhere else. And no language means no intergenerational proliferation of conceptual language; hence no scientific or technological advancement as we know it. So the overwhelming likelihood is that we are all alone in this respect.
