A Brief History of Artificial Intelligence

December 1, 2020
A chronicle of 70 years of progress in artificial intelligence that delivers encouraging news. Wooldridge, the head of the computer science department at Oxford, emphasizes that AI researchers have spent huge amounts of effort and money and "repeatedly claimed to have made breakthroughs that bring the dream of intelligent machines within reach, only to have their claims exposed as hopelessly overoptimistic. As a consequence, AI has become notorious for boom-and-bust cycles." As of 2020, computers perform useful tasks that humans find tremendously difficult, but they are not terribly smart. The author reminds readers that a computer is a machine that follows simple instructions rapidly--billions of times faster than a human. Computers can make decisions provided they're given instructions on how; if they receive proper guidance, they can adjust and learn. Machine learning, an impressive 1990s advance, produced computers that won on Jeopardy! and were able to take the initiative when given an order, beginning with the iPhone app, Siri, in 2010. A fine educator, Wooldridge lays out the problems solved since the end of World War II, illustrating how far we have come and how far we still have to go. Calculating and sorting proved to be easy. After a great effort, computers now play complex board games (e.g., chess), recognize faces in pictures, answer medical questions better than most doctors, and translate words in real time. Impressive progress in driverless cars and automatic captioning for pictures has convinced Wooldridge that further breakthroughs are imminent. As for problems requiring human-level general intelligence--producing genuine art, communicating with a person and understanding--these are far from being solved. Wooldridge shows little sympathy with "scaremongering" about "killer robots," but he admits that a future with intelligent machines will see profound social changes, which pundits are happy to describe in the full knowledge that predictions are usually wrong. Robot butlers are not on the horizon, but this is an insightful update on the digital revolution still in progress.

Computer science professor Wooldridge (An Introduction to MultiAgent Systems, 2011), an expert on artificial intelligence (AI), covers the history of AI and the important facets of the field. When we think of AI, we think of driverless cars or robot helpers. According to Wooldridge, there are many exciting possibilities with AI, but also misconceptions about it. He explores the development of technical terms and algorithmic concepts in AI and highlights the ideas, projects, and people involved in the field. Drawing on his own research experiences, he shares his thoughts on AI's impact in areas such as health care and transportation. Geared toward general readers, Wooldridge's writing is accessible. The content can be demanding, though, as he often presents complex analogies and systems of thinking in AI. Readers interested in AI, semantics, and the history of technologies will find this book fascinating and engaging in its examination of the impact and development of AI in our society and lives today.
