To Infinity...

Leo: My generation never got the future it was promised... Thirty-five years later, cars, air travel is exactly the same. We don't even have the Concorde anymore. Technology stopped.

Josh: The personal computer...

Leo: A more efficient delivery system for gossip and pornography? Where's my jet pack, my colonies on the Moon?

-West Wing season 5

I think what's kind of neat about this book isn't all the things we still haven't accomplished but all the things we have, far more efficiently than the author dreamed.  But a jet pack would be awesome.
