The effects of generative AI are already being widely felt as 11% of tasks done by workers are currently exposed, the Institute for Public Policy Research (IPPR) said.

It said that back office, entry level and part-time jobs were at the highest risk of being disrupted during the so-called first wave, with women and young people the most likely to be affected as a result.

But its analysis showed that as more employers integrate AI technology into their work processes, up to 59% of tasks would be hit without government intervention, leaving the low-skilled most exposed.

The figure equated to 7.9 million roles, the report said, adding that such a shift would provide no benefit to gross domestic product (GDP).

The authors described that as the "worst case scenario".

But they painted a more positive picture for the economy, and people, if the transition was effectively managed through an industrial strategy that placed an emphasis on protecting key human functions through regulation and that aimed to unlock investment, particularly in training.

They claimed this could lead to an economic boost of 13% to GDP, around £306bn a year, in the best case.

The government is yet to bring forward any legislation specifically aimed at the rise of AI, but last month did announce plans to spend more than £90m on new AI research hubs that will look into ways of using AI responsibly across areas such as healthcare, chemistry and mathematics.

Carsten Jung, senior economist at the IPPR, said: "Already existing generative AI could lead to big labour market disruption or it could hugely boost economic growth, either way it is set to be a game changer for millions of us.

"Many firms are already investing in it, and it has potential to speed up many more tasks as more businesses adopt it.

"Over the next five years it could transform knowledge work.

"The question now is less whether AI can be useful, but rather how fast and in what manner employers will use it.

"History shows that technological transition can be a boon if well managed, or can end in disruption if left to unfold without controls."

A spokesperson for the Department for Science, Innovation, and Technology, said: "This research is hugely speculative.

"There are numerous reports which also predict AI will spark a huge creation in jobs, unlocking further growth and ramping up productivity.

"AI already contributes more than £3.7bn to our economy every year and we have already invested £290m since 2018 in skills and talent initiatives for the jobs of the future.

"We continue to assess the impact of AI on different sectors and ensure employers play a leading role in building robust UK skills and talent. We are also working with Innovate UK and the Alan Turing Institute to develop guidance on the core AI skills people need, which will be published later this year."

Recruitment & Employment Confederation deputy chief executive Kate Shoesmith said of the findings: "Some employers are using AI well, such as in scheduling, sourcing candidates, background checks and personal development plans. But we are only at first base in what AI can do for the labour market.

"We can help maximise the benefits of AI if employers and government work together, particularly on skills development and compliance.

"It's a fast-moving area - one where we need people proficient and trained in using AI as it is now but also given the skills to adapt to future developments. So, the education system needs to be built around these core employer needs, with flexibility to fund appropriate short-course training, as would come from a more flexible Apprenticeship Levy."
