Artificial intelligence, once confined to the realm of science fiction, is changing our lives.
Cars are driving themselves. Drones are being programmed to deliver packages. Computers are learning to diagnose diseases.
In a recent book, economists Erik Brynjolfsson and Andrew McAfee describe these recent advances as examples of the beginning of what they call "the second machine age".
The very name - the first machine age was the Industrial Revolution - suggests an epochal shift. And, indeed, if the predictions are to be believed, these technological advances could have profound implications for the way we live.
One common forecast is that as ever-more-advanced robots substitute workers, the cost of labour will become less important, and manufacturing will move back to rich countries.
Another is that increasingly intelligent machines will reduce the demand for advanced skills, and the economic advantage of having these skills will decline as a result.
The first of these two hypotheses remains far-fetched. But there is evidence that the second has already started to come to pass, with serious implications for the way that modern economies have attempted to meet the challenges of globalisation.
To be sure, there has been plenty of anecdotal evidence of "reshoring" - the relocation of jobs from low-wage countries to high-wage economies.
Apple is shifting some manufacturing from China to Silicon Valley; Airtex Design Group is moving part of its textile production from China back to the United States.
In a recent survey of 384 firms in the euro zone by management consultancy PricewaterhouseCoopers, two-thirds of the respondents said they had reshored some activities during the past year, and 50 per cent plan to do so in the next.
But when one looks at the data, there is no sign of reshoring. Indeed, the trend is continuing in the opposite direction.
Offshoring dropped during the Great Recession that followed the 2008 financial crisis, but quickly rebounded, accelerating past pre-crisis levels. For the moment, the return of manufacturing to rich countries remains a prediction, not an outcome.
Evaluating the second hypothesis is more complicated. At first glance, the evidence supports the possibility that demand for advanced skills is falling.
With the exceptions of the US and Germany, the wage gap between skilled and unskilled workers has been declining in all Western countries in the last 17 years.
One possible explanation is that education levels in Europe outstripped the pace of technological change, oversupplying the market for advanced skills.
