Artificial Intelligence \u2013 or AI for short \u2013 is often depicted in films in the shape of helpful droids, all-knowing computers or even malevolent \u2018death bots\u2019. In real life, we\u2019re making leaps and bounds in this technology\u2019s capabilities with satnavs, and voice assistants like Alexa and Siri making frequent appearances in our daily lives. So, should we look forward to a future of AI best friends or fear the technology becoming too intelligent. Tim Harford talks to Janelle Shane, author of the book \u2018You Look Like a Thing and I Love you\u2019 about her experiments with AI and why the technology is really more akin to an earthworm than a high-functioning \u2018death bot\u2019.
