More about the book
Journey from Claude Shannon's mathematical theory of communication in 1948 to the transformer revolution of 2017 and beyond. Witness the symbolic AI winters and statistical summers. Understand why ELIZA fooled people in 1966, how hidden Markov models conquered speech recognition, and what made attention truly 'all you need.' Each breakthrough is placed in its historical context, showing not just what was discovered, but why it mattered.
This isn't just a timeline of papers and patents. It's a narrative of human ingenuity. You'll meet the researchers who spent decades on problems the world had forgotten, the skeptics who were proven wrong, and the visionaries who saw what was coming. From Turing's imitation game to GPT-4's emergent abilities, from hand-crafted rules to trillion-parameter models, the arc of progress reveals patterns that illuminate where we might be heading next.
Whether you're an AI practitioner seeking context for your work, a student wanting to understand the field's intellectual heritage, or simply curious about one of the most consequential technological developments in human history, this comprehensive chronicle delivers the complete story of how we taught machines to understand language.
