In this episode of Futuropolis, we tackle the age-old question: what is love? Okay, we don’t actually answer that question, but, we do talk to a sociologist at Tinder, the co-founder of OkCupid, and a sociologist who has studied how the ways through which we find mates has changed over time. Plus, we take an entertaining look back at our archives to see why people were marrying young back in 1960. In the end, we think we have a pretty good handle on how technology is butting into our love lives. For better or for worse. (In sickness and in health.) And when all else fails, we ask Siri.
