It is barely 20 years since Sergey Brin and Larry Page registered the domain name google.com, and only 10 years since Steve Jobs walked onto a stage in San Francisco and introduced the iPhone. Yet in this short period, digital technologies have upended our world. We introduced the Digital Evolution Index in HBR in 2015 to trace the emergence of a “digital planet,” how physical interactions — in communications, social and political exchange, commerce, media and entertainment — are being displaced by digitally mediated ones. We identified many hotspots around the world where these changes are happening rapidly and other spots where momentum has slowed. Two years on, depending on where we live, we continue to move at different speeds toward the digital planet.
