This week, an update on the legal battle between Meta and former Facebook moderators in Kenya. One of them, Trevin Brownee, tells our reporter Chris Vallance that reviewing the most extreme content on the internet cost him his "human side." We ask what's the human cost of keeping the internet safe, and what do we owe those who do that work for us? Also this week, the weird and wonderful sounds of quantum computers in action. Professor Winfried Hensinger, who heads the Sussex Ion Quantum Technology Group and is the director of the Sussex Centre for Quantum Technologies, explains how they could change the world. And Professor Stephen Brewster, of the University of Glasgow’s School of Computing Science, and his colleague Ammar Al-Taie, on the difficulties of getting driverless cars to understand the complex and subtle interactions between cyclists and drivers.
