Hmm. Here's another thought probe: of the list of people whom you would like to bring back because what they accomplished while they lived gave an indication of how much more they could have contributed had they not died prematurely (careful, here it comes), who can you think of who probably would have totally it screwed up, managed to negate their earlier accomplishments, turned out to be nothing more that a flash-in-the-pan, and eventually died in obscurity?
