After four years following the story, our host Nicky Woolf brings us a new twist to "Havana Syndrome". In 2016, diplomats reported a strange burst of sound — followed by months of debilitating symptoms. “Havana Syndrome” sparked questions and conspiracy theories across the web about a possible unseen weapon. Now, new reports from Norway describe a scientist experiencing similar effects after testing a microwave device. Nicky asks: if such technology exists, who owns it and what are they doing with it next?

Also on The Interface this week: At the landmark trial in LA, social media companies like WhatsApp, Facebook and YouTube are defending their platforms against the accusation that they are addictive to young people; we ask what the fall out from the trial will be and what legal clause, Section 230, that dates from 1934 really means in the social media age. Plus, host Karen Hao has spend the week rubbing shoulders with the great and the good from the AI companies at the AI Impact Summit in Delhi, but what really goes on the shadowy meeting rooms around the fringe?

The Interface is your weekly guide to the tech rewiring your week and our world. Hosted by journalists Thomas Germain, Karen Hao, and Nicky Woolf, each episode unpacks week-by-week the unfolding story of how technology is shaping all of our futures. No guests. No jargon. Just three sharp voices debating the tech stories that matter - whether they shook a government, broke the internet, or quietly tipped the balance of power.
