Where is technology going?

In the past there has been some considerable breakthroughs in technology from the introduction of the CD to the sudden craze of High-Definition TVs. With all of these new ideas and improvements to current technology happening around us, one has to ask, "where do we go next?" The next big thing seems to be OLED TVs which are the thinnest HD quality televisions to come to the market, but even these are still getting worked on. There always seems to be something else around the corner but i often think, what if, one day we run out of ideas?
The introduction of the MP3 player brought a new way to listen to music, but whats next? What other method will be discovered? This is the case with many sides of the market and we find ourselves getting caught up in the latest craze and discarding our older products, however, i just hope this cycle does not one day end and we are delved into the dark ages.
