We have seen the future of ubiquitous computing, and it's gloomy. While the various technologies keep advancing at a breakneck pace, and half of human race are already carrying computing systems with them, the goal of transparently integrating all those devices and networks to usable ubiquitous systems seems to be receding further away every day. We are seeing around us major shortcomings in terms of usability, interoperability, and security, and expect that the situation in integrated systems will only get worse. The next decade will bring wonderful advances in individual devices, services and technologies, but the overall picture is not as rosy. In this chapter, we discuss the drivers of this undesirable development, while also observing some signs of more positive trends.
