Book Spotlight: Reclaiming Your Role in the AI Era
In an age where algorithms influence everything from our morning playlists to our career paths, it’s easy to feel like a passenger in a vehicle we don’t control. A new book by industry veteran Marcus Fontoura aims to change that narrative. (Digital Agency Book, 2026)
Human Agency in a Digital World
Understand technology and make it work for you
This may be the first true AI-era self-help book—not because we need help using technology, but because we need help using it well. Understanding how algorithms work is the first step in making sure they work for us.
This book is about reclaiming our role, not as passengers, but as pilots, in the fast-moving journey of technological change.
Written by a computer scientist who is also a father and a teacher, this is a deeply personal and accessible guide to the systems shaping our lives.
Why This Book Matters Now
Digital agents are all around us. They suggest songs, answer questions, sort emails, and, often invisibly, shape what we think. But how much power do we really have to redirect their impact?
In Human Agency in a Digital World, Fontoura explores the hidden architectures of modern life, including:
- Social Media & Search Engines: How they capture and direct attention.
- Cloud Computing & AI: The invisible backbone of the modern economy.
- Quantum Technologies: A look into the next frontier of computing.
Drawing from decades of experience building the backbone of the internet, Fontoura demystifies these core concepts, allowing readers to develop digital fluency without needing a computer science degree.
Beyond Optimization
Ultimately, this is a book about people. It explores how we can use efficiency not just for speed or cost-cutting, but to unlock creativity, opportunity, and well-being. With examples ranging from broken playlists to complex protein folding, Fontoura asks a profound question:
What do we want technology to do for us, and what will we do with it in return?
