i always come back to the fact that "time travel" wasn't a notion until relatively recently; simply by the fact that so little changed on a centuries-long scale, and traveling through time would essentially place you in precisely the same spot, with the same set of experiences and technologies. presently, we've the opposite problem: technology advances so quickly it's difficult / near impossible to accurately predict life in five hundred years. (making time travel VERY COMPELLING!)
