For decades, millions of people watched the same television programmes, listened to the same music and argued about the same news. We didn't necessarily agree, but at least we had something to disagree about. Then came the internet, social media and recommendation algorithms, promising endless choice and a world tailored to our individual tastes.

Now, artificial intelligence threatens to take that promise to its logical, and frankly rather absurd, conclusion: a future where everyone has their own music, their own films, their own news, and perhaps even their own version of reality.

The Last Shared Thing explores the slow death of monoculture, the rise of hyper-personalisation and capitalism's extraordinary ability to turn every aspect of human existence into something it can sell back to us. From the golden age of broadcasting to algorithmic echo chambers and AI-generated companionship, it asks what happens to society when the experiences that once brought us together become products designed for us alone.
