What worries you about the coming world of artificial intelligence? Too often the answer to this question resembles the plot of a sci-fi thriller. People worry that developments in AI will bring about the ‘singularity’—that point in history when AI surpasses human intelligence, leading to an unimaginable revolution in human affairs. Or they wonder whether instead of our controlling artificial intelligence, it will control us, turning us, in effect, into cyborgs. These are interesting issues to contemplate, but they are not pressing. They concern situations that may not arise for hundreds of years, if ever. At the moment, there is no known path from our best AI tools (like the Google programme that recently beat the world’s best player of the game of Go) to “general” AI—self-aware computer programs that can engage in common-sense reasoning, attain knowledge in multiple domains, feel, express and understand emotions and so on. This doesn’t mean we have nothing to worry about.
On the contrary, the AI products that now exist are improving faster than most people realise and promise to radically transform our world, not always for the better. They are only tools, not a competing form of intelligence. But they will reshape what work means and how wealth is created, leading to unprecedented economic inequalities and even altering the global balance of power.
It is imperative that we turn our attention to these imminent challenges. What is AI today? Roughly speaking, it’s technology that takes in huge amounts of information from a specific domain (say, loan repayment histories) and uses it to make a decision in a specific case (whether to give an individual a loan) in the service of a specified goal (maximising profits for the lender).
Think of a spreadsheet on steroids, trained on big data. These tools can outperform human beings at a given task. This kind of AI is spreading to thousands of domains (not just loans), and as it does, it will eliminate many jobs. Bank tellers, customer service representatives, telemarketers, stock and bond traders, even paralegals and radiologists will gradually be replaced by such software. Over time this technology will come to control semi-autonomous and autonomous hardware like self-driving cars and robots, displacing factory workers, construction workers, drivers, delivery workers and many others.
Unlike the Industrial Revolution and the computer revolution, the AI revolution is not taking certain jobs (artisans, personal assistants who use paper and typewriters) and replacing them with other jobs (assembly-line workers, personal assistants conversant with computers). Instead, it is poised to bring about a wide-scale decimation of jobs—mostly lower-paying jobs, but some higher-paying ones, too. This transformation will result in enormous profits for the companies that develop AI, as well as for the companies that adopt it. Imagine how much money a company like Uber would make if it used only robot drivers. Imagine the profits if Apple could manufacture its products without human labor. Imagine the gains to a loan company that could issue 30 million loans a year with virtually no human involvement. (As it happens, my venture capital firm has invested in just such a loan company.) We are thus facing two developments that do not sit easily together: enormous wealth concentrated in relatively few hands and enormous numbers of people out of work. What is to be done?
Part of the answer will involve educating or retraining people in tasks AI tools aren’t good at. Artificial intelligence is poorly suited for jobs involving creativity, planning and “cross-domain” thinking—for example, the work of a trial lawyer. But these skills are typically required by high-paying jobs that may be hard to retrain displaced workers to do. More promising are lower-paying jobs involving the “people skills” that AI lacks: social workers, bartenders, concierges—professions requiring nuanced human interaction. But here, too, there is a problem: How many bartenders does a society really need?
The solution to the problem of mass unemployment, I suspect, will involve “service jobs of love.” These are jobs that AI cannot do, that society needs and that give people a sense of purpose. Examples include accompanying an older person to visit a doctor, mentoring at an orphanage and serving as a sponsor at Alcoholics Anonymous—or, potentially soon, Virtual Reality Anonymous (for those addicted to their parallel lives in computer-generated simulations). The volunteer jobs of today, in other words, may turn into the real jobs of the future. Other volunteer jobs may be higher-paying and professional, such as compassionate medical service providers who serve as the “human interface” for AI that diagnose cancer. In all cases, people will be able to choose to work fewer hours than they do now. Who will pay for these jobs?
Here is where the enormous wealth concentrated in relatively few hands comes in. It strikes me as unavoidable that large chunks of the money created by AI will have to be transferred to those whose jobs have been displaced. This seems feasible only through Keynesian policies of increased government spending, presumably raised through taxation on wealthy companies. As for what form that social welfare would take, I would argue for a conditional universal basic income: welfare offered to those who have a financial need, on the condition they either show an effort to receive training that would make them employable or commit to a certain number of hours of “service of love” voluntarism.
To fund this, tax rates will have to be high. The government will not only have to subsidise most people’s lives and work; it will also have to compensate for the loss of individual tax revenue previously collected from employed individuals.
This leads to the final and perhaps most consequential challenge of AI. The Keynesian approach I have sketched out may be feasible in the United States and China, which will have enough successful AI businesses to fund welfare initiatives via taxes. But what about other countries?
They face two insurmountable problems. First, most of the money being made from artificial intelligence will go to the United States and China. AI is an industry in which strength begets strength: The more data you have, the better your product; the better your product, the more data you can collect; the more data you can collect, the more talent you can attract; the more talent you can attract, the better your product. It’s a virtuous circle, and the US and China have already amassed the talent, market share and data to set it in motion. For example, the Chinese speech-recognition company iFlytek and several Chinese face-recognition companies such as Megvii and SenseTime have become industry leaders, as measured by market capitalisation. The US is spearheading the development of autonomous vehicles, led by companies like Google, Tesla and Uber.
You might also want to see this:
As for the consumer internet market, seven American or Chinese companies—Google, Facebook, Microsoft, Amazon, Baidu, Alibaba and Tencent—are making extensive use of AI and expanding operations to other countries, essentially owning those AI markets. It seems American businesses will dominate in developed markets and some developing markets, while Chinese companies will win in most developing markets.
The other challenge for many countries that are not China or the US is that their populations are increasing, especially in the developing world. While a large, growing population can be an economic asset (as in China and India in recent decades), in the age of AI it will be an economic liability because it will comprise mostly displaced workers, not productive ones. So if most countries will not be able to tax ultra-profitable AI companies to subsidise their workers, what options will they have? I foresee only one: Unless they wish to plunge their people into poverty, they will be forced to negotiate with whichever country supplies most of their AI software—China or the US—to essentially become that country’s economic dependent, taking in welfare subsidies in exchange for letting the “parent” nation’s AI companies continue to profit from the dependent country’s users.
Such economic arrangements would reshape today’s geopolitical alliances. One way or another, we are going to have to start thinking about how to minimise the looming AI-fuelled gap between the haves and the have-nots, both within and between nations. Or to put the matter more optimistically: AI is presenting us with an opportunity to rethink economic inequality on a global scale. These challenges are too far-ranging in their effects for any nation to isolate itself from the rest of the world.
