Is Innovation Outstripping Our Imaginations?

Kottke reproduces a list of desired innovations written by Robert Boyle in the 17th century (Boyle was a central figure in the development of British science and the Royal Society).  Turns out we've done many of what he wanted (i.e., flying and plastics).  I wonder, and doubt, whether any one person today could come up with a similar list of innovations which will be implemented in the next 300 years.
