BRUSSELS – Like any transformative trend, the rise of artificial intelligence (AI) poses both major opportunities and significant challenges. But the gravest risks may not be the ones most often discussed.
According to new research from the McKinsey Global Institute (MGI), AI has the potential to boost overall economic productivity significantly. Even accounting for transition costs and competition effects, it could add some $13 trillion to total output by 2030 and boost global GDP by about 1.2 per cent year. This is comparable to – or even larger than – the economic impact of past general-purpose technologies, such as steam power during the 1800s, industrial manufacturing in the 1900s, and information technology during the 2000s.
Perhaps the most discussed concern about AI is the prospect that intelligent machines will replace more jobs than they create. But MGI’s research found that the adoption of AI may not have a significant effect on net employment in the long term. Extra investment in the sector could contribute 5 per cent to employment by 2030, and the additional wealth created could drive up labor demand, boosting employment by another 12%.
But while the overall picture is positive, the news is not all good. For one thing, it is possible that it will take time for AI’s benefits – particularly with regard to productivity – to be felt. Indeed, MGI’s research suggests that AI’s contribution to growth may be three or more times higher by 2030 than it is over the next five years.
This is in line with the so-called Solow computer paradox: productivity gains lag behind technological advances – a notable phenomenon during the digital revolution. This is partly because, initially, economies face high implementation and transition costs, which estimates of AI’s economic impact tend to ignore. MGI’s simulation suggests that these costs will amount to 80 per cent of gross potential gains in five years, but will decline to one-third of those gains by 2030.
The more troubling potential feature of the AI revolution is that its benefits are not likely to be shared equitably. The resulting “AI divides” will reinforce the digital divides that are already fueling economic inequality and undermining competition. These divides could emerge in three areas.
The first divide would emerge at the company level. Innovative, leading-edge companies that fully adopt AI technologies could double their cash flow between now and 2030 – an outcome that would likely entail hiring many more workers. These companies would leave in the dust those that are unwilling or unable to implement AI technologies at the same rate. In fact, firms that do not adopt AI at all could experience a 20 per cent decline in their cash flow as they lose market share, putting them under pressure to shed workers.
The second divide concerns skills. The proliferation of AI technologies will shift labor demand away from repetitive tasks that can more easily be automated or outsourced to platforms, toward socially or cognitively driven tasks. MGI’s models indicate that job profiles characterized by repetitive tasks and little digital knowhow could fall from some 40 per cent of total employment to near 30 per cent by 2030. Meanwhile, the share of jobs entailing non-repetitive activities or requiring high-level digital skills is likely to rise from some 40 per cent to more than 50 per cent.
This shift could contribute to an increase in wage differentials, with around 13 per cent of the total wage bill potentially shifting to non-repetitive jobs requiring high-level digital skills, as incomes in those fields rise. Workers in the repetitive and low-digital-skills categories may experience wage stagnation or even reduction, contributing to a decline in their share of the total wage bill from 33 per cent to 20 per cent.
The third AI divide – among countries – is already apparent, and seems set to widen further. Those countries, mostly in the developed world, that establish themselves as AI leaders could capture an additional 20-25 per cent in economic benefits compared with today, while emerging economies may accrue only an extra 5-15 per cent.
The advanced economies have a clear advantage in adopting AI, because they are further along in the implementation of previous digital technologies. They also have powerful incentives to adopt AI: low productivity growth, aging populations, and relatively high labor costs.
