response to the clip from class

I found in the clip that the future can change and technology can advance. But what i found weird was that a woman named Susan was dead in the beginning of the clip and 5 minutes later she was alive.but they  couldn't figure out if it was really her. It was strange how she remember everything expcet. In the present you wouldn't really see that i would just think it would happen as a chance like 1 to a billion. This clip can show how advance everything is. for example they have a better way to find out someones DNA a lot faster.Its a cat-scanner.Another example is the type of smart houses. it had a hidden bathroom that came out of the wall. that is a thing you don't see everyday in the present.

Boston in the future

In about 300 years I think technology will be so advanced that the city of Boston will be totally reconstructed into a futuristic, space-station looking city.
