Technologies we are familiar with today will change and evolve. Cars for example will become more efficient and as Future Cars and the Jetsons, by Bricklin will be completely electric. Another possible change in the automobile industry is the creation of a flying car, such as the ones depicted in the popular cartoon the Jetsons. Proof of the more efficient cars to come can be seen in the hybrids and hydrogen fuel cell cars being designed and tested today. Another technology that is common today that is looking at a promising future is robotics. Shigeo Hirose speculates in his essay Where Are All the Robots that robots will have a negative conotation, because robots will replace humans in the work force. In this day and age this vision is already becoming a possibility, day after day factory workers are being replaced by more efficient robots that are cheaper to maintain and don't require a paycheck. In contrast to Hirose's negative view of future robots, most people today predict humaniod robots that will be able to think for themselves and peform tasks without being told. I believe that humans will realize the faults in having a robot that can think for themself, because the life of a robot is one of servitude and as many sci-fi movies predict, any robot that can think for themself will want to be free to do as they please.
