Author event with James Arbib – Tuesday 2nd September 2025
We’re excited to announce a special evening conversation with futurist, investor and co-author James Arbib, exploring the bold and urgent vision behind his new book Stellar: A World Beyond Limits, and How to Get There.
James is co-founder of RethinkX and a leading thinker on the intersection of exponential technologies, systems change, and planetary boundaries. In Stellar, he and co-author Tony Seba argue that we are entering a civilisation-scale transformation - one in which energy becomes superabundant, institutions are reimagined, and regeneration replaces extraction as our core economic logic.
James will explore what this means for founders, investors and policymakers: how solar, wind and battery technologies could reshape everything from food and transport to ownership models and finance - and what it takes to lead in a world where legacy systems can no longer be patched.
As climate solutions scale, geopolitical tensions rise, and extractive models reach their limits, Stellar offers a radical but rigorous roadmap, not just for getting to net zero, but for building what comes next.
