In North America, the fragile peace that exists among the continent’s independent nations and city-states is under threat. The ambitious Grand Guardian of the People's Republic of America is mobilizing his massive war machine in order to make real his dream of reunifying a former great power. But on the eve of the offensive, a leading scientist dies under mysterious circumstances, though not before he entrusts another with the key to unlocking a secret.

Restore


Susan Kaye Quinn - 2015
    But Unit 7435 finds there is a price to be paid for love… and for failing in its primary mission. Restore  is a standalone short story that takes place in the world of the Singularity novels. Start the novel series with The Legacy Human (Singularity 1).A NOTE FROM THE AUTHORThe future is… unsettling.Technology isn’t just racing forward, it’s accelerating. This isn’t just our imagination, it’s a natural consequence of innovation building upon innovation. The gap between what we can imagine and reality shrinks every day. Our relationship with technology is already one of the defining issues of the 21st century. As we integrate it ever-more-intimately into our lives and bodies and brains—as we mold our creations in our own image, not only physically, but mentally and emotionally—our tech will shape us in ways we will barely understand.The 21st century will challenge us to remember what it means to be only human.But creating a truly sentient Artificial Intelligence is far more complicated than first dreamed in Asimov’s Bicentennial Man. As we learn more about the three pounds of meat and electricity between our ears, as well as consciousness itself, we are realizing how difficult the job is. In a sense, creating an AI will force us to answer some of the deepest questions humanity has ever asked… about ourselves and our place in the universe.What does it mean to create intelligence if you intentionally limit it? Is it cruel or compassionate to keep your tech from evolving above a certain sentience level?I hope Restore will provoke a bit of thought in your own personal set of three pounds of meat and electricity.
