After all, can a mayfly explore a city? It'll be dead in three days. That's us, in space.
That's a horrible analogy IMHO. I don't see any need for humans to live longer than we do. We can pass on our knowledge to anyone that wishes to have it, and now have entire decades worth of knowledge, all at our finger tips. The only thing that matters is a persons thirst for such exploration. I'd much rather delve in something that stops the aging process (yes, i know, very far fetched) not to keep us alive for longer, but to keep us young till we die. Then you wouldn't have to worry about 80 year old people driving down the road, or unable to make a contribution to society, and could get rid of "old folks homes."
It's time to boot, do your boot ROMs know where your disk controllers are?
