About The Book

We live in a world increasingly guided by algorithms. They recommend what we watch, what we buy, where we travel, and even whom we connect with. With every advance in technology, we move closer to a future where machines help shape more of our decisions.
But what if the most advanced algorithm ever created decided there were some choices it should not make?
The Last Useful Algorithm is a near-future novel that explores the limits of optimization, the ethics of artificial intelligence, and the value of human judgment. Through a story of innovation, ambition, and unexpected consequences, it asks a simple but profound question: Are all decisions meant to be solved?
At its core, this is not a book about technology. It is a book about people, their values, relationships, doubts, and responsibilities. As machines become increasingly capable of guiding human lives, the novel examines what should be entrusted to algorithms and what must remain uniquely human.
Neither a warning about the future nor a celebration of it, The Last Useful Algorithm invites readers to reflect on the choices that define us and the wisdom required to make them.
Because some decisions matter not only for their outcomes, but for the act of choosing itself.

About The Author

Hemang Gandhi is an engineering leader, product builder, and technology professional with over a decade of experience developing large-scale software products across fintech, travel, media, and emerging digital platforms. Throughout his career, he has led engineering teams, managed complex technology initiatives, and worked at the intersection of innovation, business strategy, and human decision-making.
His fascination with technology has always been accompanied by a deeper question: just because we can automate something, should we? That question became the foundation for The Last Useful Algorithm, a novel that explores the limits of optimization, the ethics of artificial intelligence, and the choices that remain uniquely human.
Drawing from years of experience building systems designed to solve difficult problems, Hemang combines technical realism with philosophical inquiry. His writing focuses on the tension between efficiency and meaning, progress and responsibility, and the growing role of intelligent machines in everyday life.
Based in India, Hemang enjoys exploring ideas about technology, leadership, human behavior, and the future. The Last Useful Algorithm is his debut novel and reflects his belief that the most important decisions in life may be the ones no algorithm can make for us.
