TEDx Doncaster 2026: Undermined From Coal to Code to AI Festival of Ideas

In October 2026, TEDx Doncaster returns with its most ambitious programme to date, a Festival of Ideas that captures the spirit, history, and future of a place that has always evolved. This year’s theme, Undermined, draws a powerful line from Doncaster’s coal-mining heritage to the digital and artificial-intelligence revolution shaping tomorrow. It is a theme rooted in both disruption and reinvention. What does it mean to be undermined? To be overlooked, displaced, or redefined? And more importantly, what comes next? Across one landmark weekend at CAST Theatre, 20 speakers will step onto the iconic red carpet to share ideas that challenge, provoke, and inspire. These are not simply stories; they are ideas with consequences. Ideas that interrogate systems, expose blind spots, and reimagine futures.
