There is no need to worry about whether robots might start taking our jobs. It's already happening.
Three of the world's 10 largest employers are already replacing tens of thousands of their workers with robots:
That is likely the tip of the iceberg. This deliberately scruffy chart from CSLA of the 10 largest global employers shows the world's biggest workforces shows the potential for axing workers in favour of machines:

Of those 10, only the UK's National Health Service - with its massive army of doctors and nurses doing unrepetitive, unique tasks - looks like hostile territory for robots. The other nine are rich with rote, repetitive tasks that might be better performed by software.

77% of all Chinese jobs could go to robots

Foxconn's 60,000 robots are only a small fraction of its 1.3 million total workers. So we're still at the beginning of our robotic future. But few people are aware of the scale of the coming revolution in work. Consider:
The vision of mass unemployment created by robots isn't a guarantee, of course. The optimistic vision of a robotic future is one where our mechanical helpers allow us to work 4-day weeks by slashing the workload, leaving us to spend most of our time in the pub or in front of the TV (let's be honest). New technology tends to create more jobs than it destroys - every robot worker will need a maker, a manager, and a maintenance person.
But the pessimistic vision of the future is more inequality - cheap robots put the low-paid and middle classes out of work while reaping more and more profits for the factory masters and fatcats at the top of the chain. The US Bureau of Labor Statistics produced this chart showing that phenomenon in news publishing. The internet has created plenty of media jobs, but not as many as were destroyed in the print sector:

'The bad version is one where ... jobs get killed faster than we create new ones'

The Citi report warned that "the benefits of technological change are not being widely shared,"and says advances in automation and robotics are likely to exacerbate the gulf between the 1% and the 99%.
Jim Snabe, a board member at WEF, set out this binary vision at the DocuSign Momentum conference in London this week, telling the audience:
There's no doubt that the opportunity for businesses to reinvent themselves. But the societal impact of that can be - will be - huge. There's a good and a bad version of that.
The bad version is one where we bet everything on that digital infrastructure and yet it's not secure, we don't know what privacy is, and jobs get killed faster than we create new ones. Then this digital revolution will just be an ordinary revolution. People won't accept the fact that there's no longer a need for them.
The good version of this is one where we begin to steer the innovation towards a path where we use the opportunity to get independent limited resources - we stop climate change, we empower 4 billion people who are today not connected to the world.
The optimistic vision sounds very optimistic and, unfortunately for everyone, it looks like the pessimistic vision is so far making better progress than its rival - particularly in China.
25% of all robots shipped in 2014 went to China
Two recent notes from CLSA and Bank of America Merrill Lynch draw attention to just how rapid the change is happening there. It a note on "Human Capital", BoAML says: "China has the fastest adoption of robots in the world and purchased over 57,000 industrial robots in 2014 (25% of global shipments). We believe China will witness a 25%+ CAGR in annual demand for new robots during 2014-18E."
Twenty-five percent of all the world's robots!McDonald's, which employs 1.9 million people to Walmart's 2.1 million, could even embrace the robot.
McDonald's, which employs 1.9 million people could even embrace the robot. McDonald's chief executive Ed Rensi told Fox Business that if minimum wage in the US rose, the fast-food chain would consider robots, according to CSLA's Seagrim. "It's cheaper to buy a $35,000 robotic arm than it is to hire an employee who is inefficient making $15 an hour bagging French fries," he told the broadcaster.

Rise of the new Luddites?

Seagrim starts his note by referencing the Luddites, the machine breakers of 19th century England, quoting the incredible fact that: "In 1811 more British soldiers were deployed fighting Ned Ludd and his army of unemployed textile workers in the North of England than were engaged fighting Napoleon in Spain!" Clearly machines stealing jobs is not a new phenomenon.
Despite the pace of change, Seagrim believes the outcome won't be as violent as the Luddite era: "In a human-machine study conducted by an MIT professor at a BMW factory, it was shown that teams made of humans and robots collaborating efficiently can be more productive than teams made of either humans or robots alone. The cooperative process reduced human idle time by 85%."
That may be great in theory but as WEF's Snabe points out, humans need a concerted and conscious effort from businesses to include them rather than just focusing on the bottom line.
He told the conference: "The societal impact is huge and I think we have an opportunity and an obligation as business leaders to think in that direction rather than simply optimising for the next quarter. What are we going to do to make sure there are relevant jobs - they will be different jobs - for the future.
He added: "We talk about the fourth industrial revolution - the second one was electricity. Well, there are still 1.4 billion people without access to electricity. Imagine we use our innovation capacity to solve this, we bring 4 billion people online - this is the future that we need."
