🔍 Episode Summary Is civilisation inherently self-destructive? In this episode of Saving the World from Bad Ideas, Mark Lynas is joined by political scientist and existential risk researcher Dr Luke Kemp to tackle Bad Idea #23 "These are the best of times"

Luke unpacks what history really tells us about the fate of past societies — and how those lessons do (and don’t) apply to today’s global risks like climate change, nuclear war, and AI. They explore the role of complexity, fragility, and inequality in collapse, and why we need to reject fatalism to build resilience and renewal instead.

From ancient Rome to modern techno-capitalism, this episode explores whether doom is destiny — or a bad idea we need to outgrow.

🧠 Topics Discussed

● 📜 What “collapse” actually means, and why it’s more often transformation

● 🏛️ Why Rome never really “fell” — and neither did most civilisations

● 🌍 Global risks vs. local collapses: what makes our world different

● 🔁 The role of feedback loops, fragility, and complexity

● 🌡️ Why climate change is a multiplier of collapse, not the root cause

● 💣 Nuclear war, AI, and engineered pathogens as existential risks

● 🤖 Why AI doom scenarios may be overhyped (and misdirected)

● 🧠 “Collapsology,” survivalism, and the new secular eschatologies

● 🌱 What real resilience looks like: democracy, equity, adaptability

● 🧘‍♀️ Why pessimism is lazy — and optimism is an active choice

💬 Quote Highlights

“Collapse is rarely the end — it’s usually the start of something new.” — Luke Kemp

“Rome didn’t fall — it transformed over centuries. That’s not a Hollywood ending, but it’s a real one.”

“Climate change is a risk multiplier, not the root cause of collapse. The real danger is fragility and inequality.”

“We need to stop treating resilience like a buzzword. It’s a system of systems — democratic, equitable, adaptive.”

“The biggest myth is that doom is destiny. It’s not. We have choices.”
