New technologies

Sometimes I sit and wonder how our future will turn out to be with technology. Many people imagine cars that fly or robots but will it really happen? To tell you the truth technology worries me. I have noticed that machines have slowly and studiedly been taken the place of humans. For example work wise. Before machines were made people would hand make things. It increased the demand for work and now that we have machines, the work demand has decreased. Sooner or later there will be no need for people to work, because machines will be the ones to do everything. Ask your self… is it a good thing or a bad thing to have such advance technology. Will it help us economically in the future or will it hurt us and cause unemployment rates to increase.
