The Japanese continue to advance
robotics. Is it fluff and a toy, sure. More and more though the Japanese are developing robots. I think they will continue to lead the way in robotics to compensate for their rapidly
declining population. The
population projection for Japan is also very sobering. It mirrors our own in many ways. Currently, we have 12 people working for every person on Social Security. By 2020, we will have 5.
I hate to make generalizations too broad, but if you look at the declining population of the Western world(and oddly enough Japan is firmly tied itself to the Western world) the only way they will continue to remain competitive will be advances in productivity. Robots and AIs will allow that in ways that sheer manpower cannot.
Change is coming...
