Are robots a real threat to jobs?

Many of today's jobs are at high risk of being automated in the next two decades, according to researchers.

Oxford University and accountancy firm Deloitte warn that just over a third of jobs could be lost as automation increases and they say the worst hit will be low-skilled, low-paid workers who are five times more likely to be replaced by machines.

Some skills which computers cannot replicate will become increasingly valuable in the employment market.
