"Alien Minds" --'Artificial Intelligence Is Already Out There, and It's Billions of Years Old' (2017 Most Viewed)

Schneider offers three observations that together, support her conclusion for the existence of alien superintelligence. The first is "the short window observation": Once a society creates the technology that could put them in touch with the cosmos, they are only a few hundred years away from changing their own paradigm from biology to AI. This "short window" makes it more likely that the aliens we encounter would be postbiological. The short window observation is supported by human cultural evolution, at least thus far. Our first radio signals date back only about a hundred and twenty years, and space exploration is only about fifty years old, but we are already immersed in digital technology, such as cell-phones and laptop computers.
