Thank you for sharing this insightful article, and obviously, I wish you well in your quest for signs of intelligent life somewhere in our galaxy. But I have my doubts, based largely on Stuart Kauffman’s understanding of the inherently unpredictable “adjacent possible” in the evolution of complex adaptive systems. Consider: of all the myriad forms of vertebrate life on our planet, how many species evolved digital language that could join noun phrases and verb phrases to communicate information about phenomena outside themselves, or even in their own imaginations? Answer: one.
And even this would never have happened if a certain meteor had not slammed into the Yucatán peninsula some 65 million years ago, causing a random evolutionary reset. Tweak a few tiny variables in genetic mutation and even this—digital language—would never have happened. It was far from inevitable. So I remain skeptical that convergent evolution anywhere has the odds of achieving the linguistic breakthrough that made “intelligent” or “technologically advanced” life even possible.
