The Peloran spent a century helping us learn to build better gravtech.  We ran through what must have been thousands of years of technology in a mere century.  We created new worlds with it, both physical and virtual, and many that blend the two.  I love those worlds.  Genetic humans can enjoy them too of course, with suitable interfaces.  Thank God we got past haptic gloves and VR goggles.  They were just too clumsy for real life.  Or virtual life.
