I have not seen that episode. Thank you very much for telling me how it ends. I guess that will teach me the dangers of not seeing everything the second it airs. A couple of comments like that, and I can throw away my PVR completely, and save a lot of money.

To keep on topic, I think that many would die due to lack of food and medical technology, but it wouldn't take long to reach the technology level of 1900. The difference between then and now, is that we know it is possible. How much time was wasted because people didn't think something was possible?
