The Decade Intelligence Changed: How AI Quietly Reshaped Work, Power, and Human Thinking in the 2020S

During the 2020s, artificial intelligence quietly reshaped how work happens, how decisions are made, and how authority forms inside modern organisations. While public attention focused on tools and capabilities, a deeper shift unfolded beneath the surface: intelligence became abundant, judgment became optional, and responsibility changed shape.

The Decade Intelligence Changed is not a guide to artificial intelligence, nor a forecast of what comes next. It is a record of what changed while the world was accelerating - how preparation replaced deliberation, how certainty arrived earlier, and how human thinking adapted in ways that were rarely discussed.

Written with restraint and clarity, this book examines the subtle consequences of intelligent systems on work, power, and identity, and asks what remains distinctly human when intelligence is no longer scarce.
