Dude, just because something is faster doesn't necessarily make it better. When people start completely seperating themselves from the use of their own body, that is the day when we can kiss our world goodbye. One of the most important things we have as human beings is a physical connection to the world around us. You're a liberal and thus I would imagine are also an environmentalist like me. When the world has gotten to the point where everybody is so lazy that they ride a segway around everywhere, do you really think they are going to leave things as obsolete as say footpaths or woods intact. Can you really see somebody segwaying the Appalachian Trail? If our world actually does move in that direction we are going to turn even more into basically legless fat people who are so out of shape that it hurts them to walk from the couch to the fridge. Yeah, I think its a FANTASTIC idea to make machines that will do every basic, simple, natural job that all creatures have been doing since the beginning of time. JESUS! As if we weren't a lazy enough culture as it is!
