In October, the legendary naturalist Jane Goodall died at age 91. During her life, Goodall not only saw a lot of change in the world, but made a lot of it too.

Her field work with chimpanzees transformed how both science and the general public view our fellow primates. In later years, as an activist and conservationist, she inspired countless young people to follow her lead and change the world. And despite political leaders recently seeming to prioritize the economy over the environment, Goodall always found reasons to remain hopeful.

In September, Piya Chattopadhyay spoke with Goodall about her journey and her desire to keep sparking positive change.

This past week, Time magazine named "The Architects of AI" its 2025 Person of the Year, even as the stock market wobbled with fears of an artificial intelligence-fuelled bubble. One way to help make sense of this moment is a tech industry concept known as the "hype cycle." As The Sunday Magazine’s Pete Mitton explains, the time-tested idea suggests that, as with other new technologies before it, a crash of expectations – and markets – will likely arrive long before we truly understand how to live with AI. Until then, it’s important to understand how the cycle works – and some of the unique dangers AI hype presents.
