"The only constant is change", they say.
In this episode, Cal and Steph discuss just how drastically the world has changed and will continue to change.
From the iPhone... to the Internet... to antibiotics... to human flight... to to the sequencing of DNA... to perhaps the most important fact that humans now live more than double as long... these developments all happened within the last 100 years.
Given that things within a single lifetime can go from being inconceivable to ubiquitous, it's mind-blowing to imagine what might be come.
They use the remainder of the episode to explore what might be to come, whether it be proactive medicine, computer-brain interfaces, printed food, digital warfare, and much more.
