Re: starship-design: going the slow way

Well I read about the guy's 'generation ship' and I suppose I'd like to
try and start a thread here, since SSD has been so quiet recently.
Personally, I think that the idea's biggest flaw is the timescale
involved.  During the course of a 10,000 year journey, the ship would
become _very_ obsolete.  Also, stuff would wear out.  The ship would need
to be designed to be completely refitted from the superstructure on up,
every hundred years.  I can't really see any way to replace some things
while rotating the ship.  Next, in any society of 1,000,000 there is bound
to be a lunatic fringe whose very presence would endanger the whole ship.
Also, while the first set of crewmembers would likely be a fine and
upstanding group of folks, later generations are likely to be dissolute,
rebellious, and imprudent.  Remember the Chineese proverb "In the third
generation comes destruction."   For my money, I'd rather have a quick and
dirty 1000-man 70 year mission somewhere and right straight home again, tn
thousand years is entirely too long to wait for something to go wrong.
