The Last Plank: Artificial Intelligence and the Question of Being Human
If every plank of a ship is replaced one by one, is it still the same ship? Now replace the planks of a human life: memory with search, judgment with prediction, work with automation, conversation with a machine that answers in fluent sentences. Which plank is the last one, the one that makes us who we are?
This book climbs a ladder in five parts, from Sign through Information, Knowledge and Wisdom to the Ideal: what technology is and how it extends the human hand; how numbers, chance and evidence became the raw material of machines; how machines learn and what “intelligence” means; whether a machine can create, be alive, or have a conscience; and what AI means for work, money, power, trust and the future of the human species.
Who it is for
- Curious readers with no technical background. Every term is explained in plain words when it first appears.
- Students and instructors in philosophy, ethics, technology and society courses.
- Technical readers who want to step back and ask what their work is for. Optional Under the Hood boxes go deeper.
What is inside
- Part I, Sign: what technology is, nature and artifice, where knowledge comes from, the copyable digital world and the language of numbers.
- Part II, Information: the machine that becomes every machine, chance and evidence, from records to advice, and how machines learn.
- Part III, Knowledge: the ladder of intelligence, two ways of thinking, narrow, general and super intelligence, and whether a machine can create or be alive.
- Part IV, Wisdom: whether AI is making us dumb, the conscience of machines, the end of work, money and the state, who gets the fire, deception and theft, and twelve dark futures.
- Part V, The Ideal: the singularity, the Ship of Theseus and transhumanism, an endless field, and an epilogue.
What makes it different
- 26 chapters that move from “The Extended Hand: What Technology Is” to “The Singularity”, “The Ship of Theseus: Transhumanism” and “Twelve Dark Futures”.
- Key Idea, Thought Experiment, Real Story and Myth vs. Reality boxes that test popular beliefs against evidence.
- A Note to the Reader of 2066 closes every chapter: a letter to someone reading forty years from now about what should still hold, and what was probably a product of our moment.
- Questions to Carry into your own life and work, annotated further reading, a glossary and a timeline of ideas.
- Every factual claim rests on a source listed at the end of its chapter. Claims about products, laws and research carry a date, because they will change. The questions will not.
