My second prediction is that the largest area of impact from technological change over the next decade will come from increasing communications bandwidth. Supercomputers a hundred times more powerful than those that exist today don't look revolutionary, while ubiquitous ultra-cheap wireless broadband makes storage and processing power less important. Improvements in small scale energy storage, tech transfer from e-paper and lower power computer chips will probably help make portable personal computers more energy efficient, but for always-on augmented reality (and its sister-tech robotics) in areas with ubiquitous broadband computing off-site is the way to go.
