In this technology now making great forward strides, it is in my opinion too early to tell how these different ideas will manifest in successful usable application. But why do people always jump to negative conclusion about how effective or accepted these new technologies will become? If we have learned anything from the past century, it should be that where there is a will there is a way. The fact that there are those committed to making these ideas come to life, is a testament to the probability that we will see many if not all of these ideas come to fruition. However unrealistic some of the claims may seem, we need to remind ourselves of great minds like Nikola Tesla who was laughed at when he prophesied what has come to life in the form of the Internet, and more elementary the prediction, that the entire world would use AC power to meet every day demands for survival!
