Will intelligence remain biological or inevitably shift into designed machine successors?
Source Research Context: As explored in evolutionary discussions, technology is not an inevitable climax but a hyper-specific evolutionary strategy. Rare archaeological precedents—such as pre-pottery grinding wheels, cold-worked native copper in the Neolithic, and lodestone needles centuries before the magnetic compass—demonstrate that superior techniques frequently fail to become transformative societal engines without matching socio-ecological catalysts.
Furthermore, humanity’s radio bubble extends barely 120 light-years (from early 20th-century radio transmissions around 1905). Relative to the 93 billion light-year diameter of the observable cosmos, our detectable technosignature covers a volume fraction under 10⁻⁶ of our own galactic sector, explaining why the apparent silence is primarily an observational horizon constraint rather than evidence of cosmic desertion.
