WASHINGTON: Robots and artificially intelligent devices will take over many jobs now done by people, and experts are divided as to whether their spread will do human society more good than harm.

The Pew Research Centre said experts see a growing role for self-driving cars, delivery drones, robotic workers, smartphone-based assistants and even algorithmic journalism by 2025.

But they are divided on whether these technological advances will be helpful, with 48 per cent of respondents to Pew’s survey saying they will destroy jobs and increase income inequality.

Nevertheless, a slim majority said the technology will take over undesirable tasks and generate new kinds of human employment.

The report is not based on a randomised poll sample, but instead on an opt-in survey of people deemed experts or affiliated with certain organisations, taken between November 2013 and January 2014.

Lee Rainie, director of the Pew Research Internet Project, saidexperts see “the accelerating displacement of work that can be done more efficiently and cost-effectively” by robots.

This means “a transformation of labour, especially in the fields of transportation, fast food and medicine; freedom from day-to-day drudgery that allows people to define work in a more positive and socially beneficial way”. But Rainie said many see this as leading to “a shrinking of the middle class and expansion of the ranks of the unemployed”.

Automation is Voldemort: “Automation is (the ‘Harry Potter’ villain) Voldemort: the terrifying force nobody is willing to name,” said Jerry Michalski, founder of Relationship Economy eXpedition, a think tank of corporate executives.

“The race between automation and human work is won by automation, and as long as we need fiat currency to pay the rent/mortgage humans will fall out of the system in droves as this shift takes place.” Stowe Boyd, lead researcher at GigaOM Research, said the growing use of autonomous vehicles will take away important jobs for men such as truck and taxi drivers.

“An increasing proportion of the world’s population will be outside of the world of work — either living on the dole, or benefiting from the dramatically decreased costs of goods to eke out a subsistence lifestyle,” he said.

“The central question of 2025 will be: What are people for in a world that does not need their labour, and where only a minority are needed to guide the ‘bot-based economy?’ “Justin Reich at Harvard University’s Berkman Centre for Internet & Society, said, robots and artificial intelligence “will increasingly replace routine kinds of work — even the complex routines performed by artisans, factory workers, lawyers, and accountants. “Others were optimistic such as JP Rangaswami, chief scientist for Salesforce.com.

“The very nature of work will have changed radically by 2025, but only in economies that have chosen to invest in education, technology and related infrastructure,” he said.

“Some classes of jobs will be handed over to the ‘immigrants’ of AI and robotics, but more will be generated in creative and curating activities as demand for their services grows exponentially.

“Vint Cerf, chief Internet evangelist for Google, said: “Historically, technology has created more jobs than it destroys and there is no reason to think otherwise in this case. Someone has to make and service all these advanced devices.

“The report is based on views from nearly 1,900 respondents selected by Pew because of their background.

They were affiliated to think tanks; companies including Cisco Systems, British Telecom and Microsoft; universities such as the Massachusetts Institute of Technology; news organisations and activist groups such as the Electronic Privacy Information Centre.
