Merryn Somerset Webb is joined by Sky News economics editor Ed Conway, author of Material World, to explain why the real engines of modern life aren’t apps and algorithms—they’re the raw materials and “unseen” industries that make everything else possible. From salt and ethylene to ammonia and soda ash, Conway argues the UK (and Europe) are rapidly losing core chemical manufacturing capacity, driven by high energy costs and complacency about imports, with serious consequences for healthcare supply chains, industrial resilience and even defense. As the world pivots back toward the physical economy, from AI data centers to net-zero infrastructure, this conversation is a wake-up call for policymakers, investors and anyone who assumes critical materials will always be available on demand.See omnystudio.com/listener for privacy information.
