Heh. They’ve been talking about that since the 1940s. They were also promising that the people displaced by robots would be retrained to maintain the robots.
But instead, government got in the way . . .
The technological advances of the past 15 years have made robots possible. Economical factors have held deployment of robots back. It's still cheaper to hire humans to do most of the work that robots can do.
We are approaching the tipping point however and once the cost of human labor intersects with the cost of producing robots, we will quickly attain the necessary economy of scale to have robots assume a much larger role with respect to most menial tasks.
By the way, I think the term "robots" is outdated and will soon go away. We probably won't call them robots but more likely something more Orwellian such as "labor-saving devices" - so they don't seem as threatening.
