In this episode, Flora and Ulrich speak to Ed Finn about the complex world of algorithms. Ed tells us about the ever-increasing role that computational systems play in the 21st century. We discuss the threat that our increasingly technology-focused lifestyle poses to imagination and creativity, and what the future might hold in a world where Apple and Google determine, and often dominate, our every move: from dating and shopping, to securing good A Level grades or choosing a film to watch on Netflix. What's the difference between a useful algorithm and a damaging algorithm? And what responsibility do we have when it comes using algorithmic and computational systems?
