I agree. Imagine the chances for a man to survive if he suddenly appeared in the stone age, without losing his prior knowledge. I believe that his chances would be pretty small compared to some neolithic man in his twenties. Except, for the ones which are experienced in the history of technology, tool-making and such..., now they would become kings if not legends. On the other hand for a stone age man to come to our 21th century, the trouble of getting around our daily tasks would be a lot easier, not to mention his chances of survival. Life sure has become easier, but at the same time more complicated. We take our technology we have for granted, but let's not forget, the evolution of men hasn't been linear as it has been proved during the Middle Ages. Who knows, there could be a second "Fall of Roman Empire", in the not that distant future, and so many things lost, comparable to the fall of ancient civiliazation, especially because of the new way of storing information - virtual web, which is not touchable, like stone fragments, paper, clay tablets, etc.... This is just one of the reasons i hold history important to mankind as any other field of discipline.
