Part VIII: The Frontier
"Prediction is very difficult, especially about the future." — Niels Bohr (attributed)
Forty chapters into this textbook, you have built a comprehensive understanding of AI engineering — from the mathematics that underpin it to the systems that deploy it. Part VIII looks forward, surveying the research directions and technological trends that will shape the next generation of AI systems.
This is the most speculative part of the book, and intentionally so. Rather than presenting established techniques, Chapter 40 examines open questions, active debates, and emerging paradigms. Test-time compute and inference-time scaling are challenging the assumption that model capability is fixed at training time. World models aim to give AI systems grounded understanding of physics and causality. Neurosymbolic approaches seek to combine neural networks with structured reasoning. The path toward more general AI systems remains uncertain but is being actively explored.
Our goal is not to predict the future, but to equip you with the conceptual frameworks to evaluate new developments as they emerge. The field will change — but your foundations will not.
