Job Security.
Some great comments on here, but as John McGrew implied, millennia of labour-saving devices have only led to almost-flat unemployment percentages. Maybe not everybody can move into the boardroom, but rather than thinking of more "intelligent" jobs, think of more "human" ones. The world will still need doctors, nurses, teachers, store clerks, customer services. But, as well as the designers, engineers, managers for a new generation of tech, a huge number of artists, testers, user-interface focus groups will be needed to hone the end products. And... well... I don't know! Entrepreneurs? Childcare? Dog walkers?! The Luddites who smashed their machines couldn't guess what the people of 2011 would be doing when they realised we wouldn't be manually operating our looms, but we thought of stuff. And all of the "free" robot labour will drive down costs, so each of us will (on average) become better-off relative to our productivity. The "robot overlord" hype couldn't be more wrong; the robots will be working FOR US!
