No, the Dock Connector was around longer than the current Lightning standard. The 30-pin Dock Connector was released in 2003. The Lightning connector was released in 2012. So the Dock Connector lasted 9 years, and the Lightning connector has been around for only 6.
Looking back I can't believe the 30 pin lasted all the way through from iPods to the iPhone 4S. Lightning to me feels like it's been around so much longer than it has.
