Net Gens own the world?

I'm reading Don Tapscott's Grown Up Digital and feel quite related to the Net Gen in some ways although I'm Gen X'er myself. I love many of the great social networking services and other nice stuff on Internet. I love to both consume and share things there. I want my Facebook, Last.fm, Flickr, Twitter, You Tube, Spotify etc.
But then again in many ways the Net Gen is so alien to me. I'm not as fast, I'm not as social with my working practices etc.
But if they are so damn efficient and clever, what is left for us Gen X'ers and baby boomers to do in the work life? Should we just retire and let these guys and gals take care of the business? ;-) Or is there something we're better at? Maybe the answer is there in the book, I just need to finish it first and digest it for a while.
