Listening In: How Audio Surveillance Became Artificial Intelligence

by Toby Heys, David Jackson, Marsha Courneya

In 1945, W. Averell Harriman, US Ambassador to the Soviet Union, was presented with a carved wooden plaque of the Great Seal of the United States as a 'gesture of friendship' by a delegation from the Soviet's Young Pioneer Organization.
Unbeknownst to him, one of the first covert listening devices, invented by Leon Theremin was hidden within it and was subsequently used to listen in on the ambassador's conversations for six years before being discovered. This book uses remarkable tales like this to tell the story of how modern audio surveillance developed and its important role in the evolution of today's artificial intelligence.

Beginning with post-WW2 monitoring devices, Listening In traces an arc through the Cold War era into the present day in which state and commercial spyware can record our calls, copy messages and secretly film us. It subsequently moves into the near future where AI-assisted technologies can listen to things we have not yet said as well as digitally simulate and record our voices after we have died. Exploring how mass audio surveillance is carried out through devices such as smart phones, speakers and baby monitors and used to inform and train AI algorithms, the book provides fresh insights into how we are allowing our personal privacies to be traded for enhanced social connectivity and technological convenience. Ultimately Listening In reveals how the urge to listen and record everything that has ever been uttered is scored deeply into the technological operating systems of cultures from around the world.

This was a fascinating book.

When I first picked up this book and looked at the description it looked like a technological history of audio surveillance and it's gradual evolution into modern AI systems. I have to emphasize that is what the book is about, but what makes it special are some editorial choices, some most excellent and some annoying.

The book is divided into 4 eras: Hardware 1945 to 1960s, Mass surveillance 1960s to 1990, Self surveillance 1990 to present and Modern AI advancements.

I will start with the most straight forward part of the book, the raw history of the technology used from the humble first bugs to the AI Panopticon of today. This is the easiest part of the book to follow. The first two eras are quite exciting for all cold war enthusiasts. And the present day is fury inducing history of a public private partnership from hell that is Silicone valley.

Now I come to the most interesting part of the book. For every new piece of technology introduced the book will pause for a while to explicitly talk about its personal, moral and sociological transgressions. In this way the authors show us each individual step on the downward spiral to today s cyberpunk hellscape. Here we dive into philosophy and sociology to learn about all the unfounded self justifications for collection of all this data and their effect on the world at large.

My one gripe with this book is its rigid adherence to its format: era, technology, transgression for each example. This editorial decision makes the reading of the book feel too choppy, almost like reading a book size listicle. The editors defend this decision by arguing that it makes the book easier to navigate, but I do believe that that is what the index is for.

I can recommend this book to all people concerned about privacy and who need more ammunition against AI in the current time.
