Artificial intelligence holds only so much power in the year 2024. Sure, it could help improve your cover letter or maybe suggest a better pumpkin pie recipe. But it doesn’t nurture human life. The future may be quite different, with a million harmonious systems calibrating and updating and sustaining whatever remains of our species. But what happens when the systems that serve us begin to erode? Erika Swyler ponders such a future in her thoughtful speculative novel We Lived on the Horizon.
The walled city of Bulwark protects one of the final pockets of humanity from an unlivable Earth. Controlled by a citywide AI system, the city is a near-conscious network of interconnected systems and data. Bulwark’s citizens survive in comfort or squalor based on how much their ancestors gave to the greater good, with the city’s elite, known as the Sainted, living lavishly. But when one of the Sainted is murdered in his home and all the data records are erased, Enita Malovis and her house AI system, Nix, sense something terrible is happening to Bulwark. Systems are quietly shutting down or failing to respond. Can they find out who, or what, is suppressing the truth?
AI systems take center stage in We Lived on the Horizon, and Swyler gives spectacular voice to these nonliving entities. Lines of code hint at emotion with small color changes; long database query times with no responses suggest recalcitrance or confusion. These passages are some of the most interesting and innovative in the novel, and Swyler deliberately paces her story to stretch them to their fullest potential. Moral reflections on the relationship between humanity and machines drive Enita and Nix’s ever-evolving relationship as she tries—literally—to make him human.
Lovers of Octavia Butler or Mary Shelley will easily see We Lived on the Horizon’s direct descent from such literary giants. The novel’s core, however, feels timely and urgent, wondrous and inventive. It’s a marvel and a triumph. At its conclusion, I felt a twinge of dread as I contemplated what our own creations may do to try to sustain us.
