Deloitte said that around 3.3 million jobs could be classified as business services roles, and that of those, there was a “high chance” that 800,000 to one million jobs would no longer be performed by humans over the period.

Simon Barnes, a Deloitte partner, said that the sector’s workforce would “fundamentally change over the next 10 to 20 years”. Humans are likely to be liberated from “repetitive and highly structured” roles, while new higher-skilled positions are expected to be created to replace them.

Mark Carney, the Bank of England Governor, said last month that many of the jobs and industries we are now familiar with “will be gone tomorrow”. The rising speed of technological change threatens to make it difficult to choose a career, and for young people to plan their lives, he said.

During a commencement speech at the University of Alberta in Edmonton, Canada, the Governor said: “It is entirely unrealistic to map out the decades ahead.” He added that “many of the jobs and even the industries of today will be gone tomorrow”. As a result, Mr Carney advised graduates to be “flexible and adventurous”.
