Predictions about science in 2025, recorded 25 years ago

In 2000, Quirks & Quarks celebrated its 25th anniversary by travelling forward in time — to 2025 — to find out how science had changed in the years since. In this fictitious future, our present, Zargon the robot, wakes up a Bob McDonald clone from the year 2000 to speak with scientists about 25 years of science. It's a mindbending audio time-capsule with predictions that were oddly prescient, sometimes unsettling or wildly wrong.

The best — and worst — ideas of the last six decades

Sometimes the universe hands us a gift. Over the past year, our podcast listeners spent a total of 526,915 hours listening to our program. That's 21,954.8 days and that translates to 60 years of listening to us. So what better way to mark IDEAS' 60th year then to look back on the highlights and lowlights of the past six decades. To give you a hint on some of the picks, on the bad list: online identity management. Trickle down economics. On the good: Free Trade. Girl Bosses. Apparently open borders is still an open question. Panelists Jamie Liew, a University of Ottawa law professor and novelist; University of Toronto philosopher, Joseph Heath; and the Canadian Shield Institute’s, Vass Bednar, joined IDEAS producer Mary Lynk on stage, in front of a live audience at the Isabel Bader Theatre for this episode — the last in our special series celebrating our 60th anniversary.
