This TED Talks Daily podcast features game designer Jane McGonigal discussing the dangers of using "unimaginable" and "unthinkable" when considering future scenarios. McGonigal presents three hypothetical future scenarios—geoengineering, a zero-waste society, and climate migration—to illustrate how imagining different possibilities can improve our preparedness and problem-solving abilities. She emphasizes the importance of developing "imagination leadership skills" to anticipate both risks and opportunities for positive change. The interview concludes with McGonigal's call to action: to replace "unthinkable" with proactive engagement and collaborative problem-solving. Listeners are encouraged to assess their own "future power" by considering their readiness to face and solve challenging future events.
