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

And do we want to live in it?
