Sure. I'll say just a few words.
AI has gotten an awful lot of media hype, and I think that makes it very confusing to understand what its impact will be.
I tend to view it as much more continuous with the kinds of changes that information technology has been bringing about for the last 70 years, particularly regarding the role of automation.
There are tremendous and exciting things that AI can do. Some of them are very impressive. Many of them, unfortunately, are still very far removed from the point at which they can replace labour.
In fact, what tends to happen—and this has been true throughout the period—is that automation mainly pertains to automating specific tasks of a job rather than the entire job, and a lot of people misunderstand that. There are very few jobs that have been completely automated by technology. I looked at the U.S. census and identified occupations that had been completely automated by technology. I found only one, which was elevator operator. Other jobs were lost and other occupations disappeared because technology became obsolete or tastes changed, so we no longer have telegraph operators and we no longer have housekeepers of boarding houses.
That's been over a period in which technology has had a tremendous impact on automating tasks and affecting labour and productivity. What it means, basically, is that there's been a lot of fearmongering about AI causing massive unemployment. We've been using AI since the 1980s, and we're not seeing massive unemployment. I don't think we're going to see massive unemployment any time in the next couple of decades, but we are going to see many specific jobs being challenged or disappearing, and new jobs being created.
The real challenge of AI for the labour force is not that it will create mass unemployment but that it will require people to change jobs, to acquire new skills, to maybe change locations or to learn new occupations. These transitions are very costly, can become burdensome, and are really a very major concern.
There's a second thing I'll point out, but I don't want to be long here. Another major impact—and this has been true of information technology for the last two decades—is that AI has done a lot to increase the dominance of large firms. We see that large firms are acquiring a larger share of the markets. They're much less likely to be disrupted by innovators in the traditional Schumpeterian fashion, where the start-up comes along with the bright new idea and replaces the incumbent. That's happening less frequently.
That's important for a number of reasons, but it also affects the labour force in a couple of ways. One is that large firms tend to pay more, in part because they have advanced technology, and this tends to increase wage inequality. Information technology has been leading to boosting differences in pay, even for the same occupations. We'll see big differences so that the same job description will pay much more at a large firm.
The second thing is that partly because of that, there's a really significant talent war, with these new technologies requiring specific skills that work with the technology. I'm talking not just about STEM skills but all sorts of skills of people who have experience adapting their skills to work with the technology. They're in great demand, and large firms have an upper hand in the talent wars. They'll pay more; therefore, they can recruit more readily.
There's nothing bad with their paying more—we want labour to earn more—but at the same time, it means that smaller firms, particularly innovative start-ups, are having a harder time growing.
We see that the growth of start-ups declines in areas where large-firm hiring is predominant. That becomes sort of an indirect concern for labour.
I will just wrap it up with that. Thank you.
