I'm interested in what this exercise relates to, is it university, high school, sitting around a bong with a bunch of buddies? I don't see the payoff to this in terms of educational value.

Its equivalent to asking the question, if you killed Hitlers parents before he was born would WW2 have been prevented and what would the world look like today.

Its an exercise in academic folly.

The AIDs researcher could utterly fail. Just because two smart educated people have kids doesn't mean that the kids are saviers they could become a bigger drag on society then the Vietnam Vet.

Maybe while he was in Vietnam he saved a kid that grew up to be a researcher who cured feline aids and we don't know it.

In fact its a pretty horrible exercise, what does Edward manufacture. Maybe in 5 years we find out that he cheaped out on safetry equiptment and gave his employees cancer, or in 10 years he dumped toxins in the river. Or even better maybe he makes nuclear warheads.

You can't base your rescue on perceived value on society unless you own a Time Machine, and wouldn't you feel regret if you rescued Tozo and then went into the future and found out that she had given up her goals to do research and help the poor and decided to become a plastic surgeon to the stars. Would you then race back in time and not rescue her and in fact drown her because she kept Kristen Stewart on the screen for 10 years longer then she should have?
