The Shortest History of AI

Shortest History

by Toby Walsh

Six ideas to understand artificial intelligence today
Since Alan Turing first posed the question, ‘Can machines think?’, artificial intelligence has evolved from a speculative idea to a transformative force. The Shortest History of AI traces this evolution, from Ada Lovelace’s visionary work to IBM’s groundbreaking defeat of the chess world champion and the revolutionary emergence of ChatGPT. It also explores AI’s cultural journey, touching on classics such as Frankenstein, The Hitchhiker’s Guide to the Galaxy and 2001: A Space Odyssey.


Revealing how many ‘overnight’ successes were decades in the making, this accessible and illuminating book simplifies AI into six key ideas, equipping readers to understand where we’ve been – and where we’re headed.


‘This history of AI in six simple ideas is so informative and easy to digest. Essential reading’—Dr Karl Kruszelnicki


‘One of the world’s brightest minds takes on one of the world’s biggest topics … Delicious!’—Adam Spencer

'The Shortest History of AI' by Toby Walsh was indeed one of the books that I was very excited to read about. We all are quite aware of Artificial intelligence or AI. To many of us, it has become an integral part of our life. Hence, I was looking forward to knowing about how it came into existence and where this is going.

This book is stuffed with information, details and research data. My mind was boggled when I came across how AI was invented and its comparison to its present day use. Many people are scared to use AI because they feel threatened because they think it might take over the world. It's an essential read for everyone to know the correct use of AI and break the misconceptions.

Through this book, Walsh shares great success of AI in the past and in present. I came to know about many unknown things while reading this book. Like i had no idea about what was the full form of GPT in AI chatbots like ChatGPT. The T stands for transformer. Little details and interesting research analysis makes this book one of a kind. If you're someone who is eager to know about AI in detail, I'd definitely like to recommend this book to you.

Thank you NetGalley for the ARC! This is a short, comprehensive history of AI. While a lot of it was familiar to me, because I have read several books on the topic, there were still ideas and information here that felt new to me. I will definitely purchase a copy for my school library.

Brilliantly researched by one of the world's preeminent authorities on artificial intelligence (AI). Toby has lived and breathed, and made significant contributions to, the field of AI and reminds us that it is far from a new phenomenon, far from perfect, and far from over.

An engaging, insightful and accessible read!

Since the day computer was launched, writes Walsh, the advent of artificial intelligence had begun. The hullabaloo that now surrounds AI has been years in making. Walsh has systematically addressed the beginning and the advent of the machines, their expansion into a conscious level and the panic that now engulfs the world that it may take over.

So what is it about? In The Shortest History of AI, Toby Walsh takes us through the journey behind AI’s ‘overnight success’ to show how its recent skyrocketing popularity has been decades in the making. AI has been a part of our lives for centuries – from the first mechanical computer in 1837 to today’s chatbots, robots and self-driving cars.

But how did machines meant to follow simple instructions, read and do math become smart enough to write Shakespeare-style poetry, beat world champions at chess, and offer viable solutions to humanity’s problems? What lies in store for AI? Is it going to graduate to take over more complex jobs? If so, what might happen to our work, society, governance, healthcare – and life as we know it?

This brief history slices through the wild claims, myths and speculated threats to explain AI technology, its challenges, capabilities and how it is likely to shape the world in the future.

Pick it up this festive season.

This was a tough one to rate.
STRONG DISCLAIMER: I read a very early copy which was noted as an advanced, uncorrected early copy, so I imagine most of my qualms may be addressed with a final round of editing which is likely in progress now.

Pros: I like the structure of the book and I think Walsh really gets to the nitty gritty of what AI is, how it functions, and how it has developed over time. He clearly knows the subject and has distilled it down to the two phases of development and 6 essential ideas that comprise AI. These are super clear and explained well.

Cons: the writing was choppy and all over the place. Sometimes a timeline of an idea would be linear, the next point may work backward in history with no explainer. Sometimes a person would be discussed for several paragraphs, then be introduced, then immediately move to a new subject. There were random asides about people that were totally irrelevant to the book and could easily have been cut from “The Shortest History of AI”. Things just seemed out of order, to the point where I wondered if my digital ARC had a file issue.

All in all, I give it a three star. It helps frame AI very well and his look to the future is super insightful. Structure is awesome but execution was in need of another edit, which I expect it will have at this early stage. I would consider reading again after publication to see how the final version turns out and could easily bump it up to a 4 or 4.5 star book.

Thanks to NetGalley, the author, and Black Inc and The Experiment for the ARC.

Artificial Intelligence was formally “born” in 1956 at Dartmouth College—but its story stretches across centuries, cultures, and ideas.

Toby Walsh’s The Shortest History of AI is not just about machines, but about people, philosophies, and societies shaping the future. It covers:
* The innovators who imagined thinking machines
* Google’s surprising typo origin
* India’s ancient contributions to logic and reasoning
* The environmental, ethical, and existential challenges AI poses today

For professionals outside the tech world, this book offers a clear, witty, and accessible entry point into AI’s past, present, and future.

Sometimes, before forming an opinion, we simply need to know the story.

Walsh’s book is a quick, essential ride through AI’s past, present, and future. It gives easy insight into the making of AI, including the game-changing computers like Watson and Menace. All you need is 6 hours and AI would be on your tips, because let’s face it: we have to know something before we opine on it.

[ROLLAND Florence · Rating 3 out of 5]

This book would probably be excellent after being reviewed by a good technical editor. In its current state, it lacks structure.

There are lots of anecdotes in there that range from useful to just entertaining. Some will really help you understand what AI is and how it came to be. The others will just waste your time, especially in a condensed book that is supposed to cut through the babble.

I would also have liked schemas, a high level view that explains how different fields relate to each other. It is a lot easier to explain complex technical things if you provide a way to visualize them.

All in all, I enjoyed it despite the structural flaws. The author seems like a very fun and witty person, with the typical academic mindset that I love. Definitely someone fascinating to have coffee with, or spend around 100 pages sitting with.

Thank you #NetGalley and The Experiment Publishing for the ARC.

I was already sceptical both of the subject matter and of the dull, broski, pop-fiction-esque writing style of this book, but finally decided to DNF this when, ten pages in, the gentleman writer went to introduce Ada Lovelace, which he did not by describing her talents and achievements but by naming her father, Lord Byron, her friend, Charles Babbage, and then listing four paragraphs' worth of Babbage's accomplishments.

Amazing read!

My favourite part of this book was how much I "learned how much I have to learn". The field of AI is huge, growing, and excitingly unpredictable. There's so much to know about it, and this book is about the best job you could do of introducing AI to any audience.

[Sebastian · Rating 3 out of 5]

Interesting reading but a bit too technical for me at times. Toby Walsh does a great job explaining how AI evolved and where it’s going, but some sections felt heavier than needed for such a short book. Still, it’s a solid intro if you’re curious about AI and don’t mind a few deep dives!

[Stuart Robinson · Rating 5 out of 5]

An excellent - and indeed short - history of AI, exploring key themes and introducing the waves of AI development.

[Peter Baker · Rating 5 out of 5]

Fantastic dive into the history of AI with an interesting Australian perspective
