Hint: They can’t
People have it all wrong. And it’s not the first time.
Robots are going to take your job? No doubt. But your next job will pay so much more that you may decide to cut your work hours. How does 20 hours a week sound?
We’re all going to get richer. The more that AI and robots can do for us, the richer we will get.
Wealth is goods produced. AI and robots will make everyone’s labor far more productive. More wealth in the whole economy will be the result.
If robots make it much easier to do things, then a lot of factors of production will be freed up. If a robot-run factory cuts costs in half, then the saved half is available to fund more production, either of the same product or other products across the economy.
For as long as we have records, cost-savings have been reinvested, except for a tiny percentage going to the owners’ personal consumption.
More investment means more goods produced, which means a drop in the cost of living, which means a rise in the standard of living.
But will you be able to participate in it? If your job is replaced by AI or a robot, will you be able to find a new job? Will you be able to earn some money and thus be able to take part in this bonanza?
Yes.
How do I know that? How do I know that the robots won’t be doing everything, leaving nothing for human beings to earn money doing?
The temptation is to answer by finding things robots won’t ever be able to do. “Robots will never be great chefs.” “Robots will never be venture capitalists.” “Robots will never write a first-rate symphony.”
That’s irrelevant. The point is that even if AI and robots could do everything better than any human being, that would enhance, not undermine, the value of human labor.
Why? The explanation comes from applying here an important truth discovered two centuries ago. In 1817, the great English economist David Ricardo identified “The Law of Comparative Advantage.”
Ricardo was concerned with trade between nations. His Law shows that even if a given country produces everything more efficiently than another country does, it pays both countries to specialize in what they do best and trade with each other..
The Law of Comparative Advantage applies much more widely than to international trade. It used to be illustrated by considering a CEO and his typist—back when there were typewriters and typists. Even if the CEO can type faster than a given typist, it pays him to hire that typist because off-loading the typing work saves him time. He can then use that saved time in the area of his comparative advantage: running the company.
Likewise, even if there comes a time when the robots can do everything better and faster than human beings, more wealth will be produced if robots and humans each specialize in what they do best.
Super-robots would produce more for us if we save them from having to do things that are less productive.
(Of course we won’t be trading with robots: robots own nothing. Robots are owned by people, and those people will be paid for selling robots or for renting them out, just as you can rent power tools from Home Depot today.)
The Law of Comparative Advantage means humans will never run out of productive work to do. There will always be tasks that you don’t want to waste your rented or owned robots’ time in doing.
If you’ve got a robot building you a swimming pool, you don’t want him to stop to cook you dinner.
A chainsaw is a lot more efficient than a knife at cutting. But you don’t use a chainsaw to slice a loaf of bread. Particularly not if that chainsaw is being used by a robot to clear a place for a tennis court in your backyard.
So, rather than panic over “the rise of the machines,” let’s bear in mind the Law of Comparative Advantage and a couple of simple facts.
The need to economize.
No matter how fantastic the robots’ abilities become, the robots will never be able to do everything at once. Will you set them to building you a bigger house? Or designing and constructing a rocket ship to take you to Mars and back? They can’t do both at the same time.
Plus, creating the rocket ship will take staggeringly more resources and robot-hours than building the house. You’ll have to obtain materials for either project. How will you to that? By paying with money. Can you pay with robot-hours? . You have to buy or rent the robots. Money is not going away.
Suppose you, poor soul, own only two robots. Just building a new house for you will take them 6 months. Maybe you should rent a few more robots to speed the project along. Or is that a waste of robot time?
If you own robots outright, you can have them make additional robots. But that takes time. And it takes raw materials that you have to purchase. Can you afford to make or rent more robots and more materials?
And you naturally want more land for your new house. Land is in limited supply. It has to be paid for. What would you have to give up to get more land? Is it worth it?
These are economic issues. They require comparing values, making trade-offs, figuring “opportunity costs”—the factors that give rise to markets and prices.
Even with science-fictional super-robots, there will still be money changing hands and a price-system, just as now. You will still be paid for working—in the field of your comparative advantage.
New kinds of jobs will appear, as they always have when technology advances. Ironically, most of the jobs people are afraid of losing—such as programming jobs or truck-driving jobs—were themselves created by technological advances. There used to be an American saying: “Adapt or die.” Having the same kind of job as your father and grandfather did is not the American dream.
What new types of job will be created? I can no more project that than a man in 1956 could have projected that today there would be jobs in something called “social media”; or that money can be made by driving for Uber and by renting out living space through AirBnB.
The robots will make work much easier, more interesting, and much better paid.
Prepare to be enriched.
