I firmly believe that the rapid evolution of computer technology (as described in Robotic Nation) will bring us smart robots starting in a 2030 time frame. These robots will take over approximately 50% of the jobs in the U.S. economy over the course of just a decade or two. Something on the order of 50 million people will be unemployed.
Why should YOU care? Well, a 10 year-old can reasonably expect to live to 2080, and his/her children could live to around 2120, and Marshall expects robotics to be rockin' by 2050. Will North America have "socialist" systems for the life-time unemployed, or will they be left to starve, or be rounded up for "disposal"? Will there be a Luddite revolt? Makes the fixation of U.S. business on continuous quarterly growth irrelevant, dangerously so, considering the damage that mind-set has already caused.
