Since Elon Musk's acquisition of Twitter in 2022, many users have looked for alternatives, fuelling a wave of online migration from the social media platform. How do alternative platforms such as Mastodon or Bluesky differ from traditional social media, and what does the future hold for these online spaces? In this episode, we speak to Robert Gehl, Ontario Research Chair of Digital Governance at York University, Canada, about the evolving landscape of decentralised social media.

Where support for Germany’s far-right AFD is growing and why
As Germany heads towards elections on February 23, the far-right Alternative for Germany (AFD) is polling in second place on 20% of the national vote. The AFD's roots are in nationalistic and racist movements. It continues to take an ultra anti-immigration stance and is calling for "demigration" – effectively the deportation of migrants. In this episode, Rolf Frankenberger, an expert on right-wing extremism at the University of Tübingen in Germany, talks to Laura Hood, senior politics editor at The Conversation, about where the AFD draws its support from and what type of Germany it wants to return to.This episode was Mend Mariwany and Gemma Ware with sound design by Michelle Macklem.

How close are quantum computers to being really useful?
Quantum computers have the potential to solve big scientific problems that are beyond the reach of today’s most powerful supercomputers, such as discovering new antibiotics or developing new materials. But to achieve these breakthroughs, quantum computers will need to perform better than today’s best classical computers at solving real-world problems. And they’re not quite there yet. So what is still holding quantum computing back from becoming useful?We speak to quantum computing expert Daniel Lidar at the University of Southern California in the US about what problems scientists are still wrestling with when it comes to scaling up quantum computing, and how close they are to overcoming them.This episode was written and produced by Gemma Ware and Katie Flood with production assistance from Mend Mariwany and sound design by Michelle Macklem.

Silicon Valley’s bet on a future of AI-enabled warfare
From Gaza to Ukraine, today’s war zones are being used as testing grounds for new systems driven by artificial intelligence. Billions of dollars are now being pumped into AI weapons technology, much of it from Silicon Valley venture capitalists.In this episode, we speak to Elke Schwarz, a reader in political theory at Queen Mary University of London in the UK who studies the ethics of autonomous weapons systems, about what this influx of new investment means for the future of warfare.
