Human-Computer ‘Super-minds’ Redefine the Future of Work

Recently, the Trends editors presented a Webinar about the impact of AI and other digital technologies on economic growth and productivity. (If you missed it, we’ve included a link in this month’s printable edition.) The focus was on ways that the synergy between human and machine intelligence would create economic value far in excess of the sum of the parts. If, and by what mechanism this will happen, is currently the subject of intense debate in scientific, business, and government circles.

This ongoing, and sometimes loud, debate about how many and what kinds of future jobs smart machines will leave for humans to do is missing a salient point; that is, “Just as the automation of human work in the past allowed people and machines to do many things that couldn’t be done before, groups of people and computers working together will be able to do many things in the future that neither can do alone now.”

To think about how this will happen, it’s useful to contemplate an obvious but not widely appreciated fact: Virtually all human achievements ? from developing written language to making a turkey sandwich ? require the work of groups of people, not just lone individuals. Even the breakthroughs of individual geniuses like Albert Einstein weren’t conjured out of thin air; they were erected on vast amounts of prior work by others.

According to MIT professor Thomas W. Malone, human groups that accomplished all these things can be described as “superminds.” In his ground-breaking new book Superminds: The Surprising Power of People and Computers Thinking Together, Malone defines a supermind as “a group of individuals acting together in ways that seem intelligent.”

Today, superminds take many forms including:

- the hierarchies in most businesses and other organizations;

- the markets that help create and exchange many kinds of goods and services;

- the communities that use norms and reputations to guide behavior in many professional, social, and geographical groups; and

- the democracies that are common in governments and some other organizations.

All superminds have a kind of collective intelligence, an ability to do things that the individuals in the groups couldn’t have done alone. What’s new is that machines can increasingly participate in the intellectual, as well as the physical, activities of these groups. That means we will be able to combine people and machines to create superminds that are smarter than any groups of individuals our planet has ever known.

To do that, we need to understand how people and computers can work together more effectively on tasks that require intelligence. And for that, we need to define intelligence.

As Professor Malone observes, “The concept of intelligence is notoriously slippery, and different people have defined it in different ways. For our purposes, let’s say that intelligence involves the ability to achieve goals. And since we don’t always know what goals an individual or group is trying to achieve, let’s say that whether an entity “seems” intelligent depends on what goals an observer attributes to it."

Based on these assumptions, we can define two kinds of intelligence. The first is specialized intelligence, which is the ability to effectively achieve specific goals in a given environment. This means that an intelligent entity will do whatever is most likely to help it achieve its goals, based on everything it knows. Stated even more simply, specialized intelligence is “effectiveness” at achieving specific goals. In this sense, then, specialized collective intelligence is “group effectiveness,” and a supermind is an effective group.

The second kind of intelligence is more broadly useful and often more interesting. It is general intelligence, which is the ability to achieve a wide range of different goals effectively in different environments. This means that an intelligent actor needs not only to be good at a specific kind of task, but also to be good at learning how to do a wide range of tasks. In short, this definition of intelligence means roughly the same thing as “versatility” or “adaptability.” In this sense, then, general collective intelligence means “group versatility” or “group adaptability,” and here, a supermind is defined as a versatile or adaptable group.

This raises the question: What kind of intelligence does a computer have?

The distinction between specialized intelligence and general intelligence helps clarify the difference between the abilities of today’s computers and human abilities. Some artificially intelligent computers are far “smarter” than people in terms of certain kinds of specialized intelligence. But one of the most important things most people don’t realize about AI today is that it is all very specialized.

Google’s search engine is great at retrieving news articles about baseball games, for example, but it can’t write an article about your son’s Little League game. IBM’s Watson beats humans at Jeopardy! but the program that played Jeopardy! can’t play tic-tac-toe, much less chess. And, while Tesla’s cars can sort of, drive themselves, they still can’t pick up a box from a warehouse shelf.

Of course, there are computer systems that can do these other things. But the point is that they are all different, specialized programs, not a single general AI that can figure out what to do in each specific situation. Humans, with their general intelligence, must write programs that contain rules for solving different specific problems, and humans must decide which programs to run in a given situation.

In fact, none of today’s computers are anywhere close to having the level of general intelligence of any normal human 5-year-old. No single computer today can converse sensibly about the vast number of topics an ordinary 5-year-old can, not to mention the fact that the child can also walk, pick up weirdly shaped objects, and recognize when people are happy, sad, or angry.

How soon, if ever, will this change? Progress in the field of artificial intelligence has been notoriously difficult to predict ever since its early days in the 1950s. When researchers Stuart Armstrong and Kaj Sotala analyzed 95 predictions made between 1950 and 2012, about when general AI would be achieved they found a strong tendency for both experts and nonexperts to predict that it would be achieved between 15 and 25 years in the future, regardless of when the predictions were made. In other words, general AI has always seemed about 20 years away for the last 60 years.

More recent surveys and interviews tend to be consistent with this long-term pattern: As of 2018, lay people and AI experts both still predict that general AI will be here in about 15 to 25 years. So while we certainly don’t know for sure, there is good reason to be skeptical of anyone confidently predicting that general AI will appear in the next couple of decades. MIT’s Malone believes that, barring some major societal disasters, it is very likely that general AI will appear “someday,” but probably not until quite a few decades in the future. The Trends editors agree.

Until then, all uses of computers will need to involve humans in some way. In many cases today, people are doing parts of a task that machines can’t do. But even when a computer can do a complete task by itself, people are always involved in developing the software and usually modifying it over time. They also decide when to use different programs in different situations and what to do when things go wrong.

Given the inevitable synergy between them, how can people and computers work together to create value?

According to Malone, one of the most intriguing possibilities for how people and computers can work together comes from an analogy with how the human brain is structured. There are many different parts of the brain that specialize in different kinds of processing, and these parts somehow work together to produce the overall behavior we call intelligence. For instance, one part of the brain is heavily involved in producing language, another in understanding language, and still another in processing visual information. Marvin Minsky, one of the fathers of AI, called this architecture a “society of mind.”

Minsky was primarily interested in how human brains worked and how artificial intelligence programs might be developed, but his analogy also suggests a surprisingly important idea for how superminds consisting of both people and computers might work: Long before we have general AI, we can create more and more collectively intelligent systems by building societies of mind that include both humans and machines, each doing part of the overall task.

In other words, instead of having computers try to solve a whole problem by themselves, we can create hybrid “cyber-human systems” where multiple people and multiple machines work together on the same problem. In some cases, the people may not even know ? or care ? whether they are interacting with another human or a machine. People can supply the general intelligence and other skills that machines don’t have. The machines can supply the knowledge and other capabilities that people don’t have. And, together, these systems can act more intelligently than any person, group, or computer has done before.

How is this different from most current thinking about AI? Many people today assume that computers will eventually do most things by themselves and that we should put “humans in the loop” in situations where people are still needed. But it’s probably far more useful to realize that most things now are done by groups of people, and we should put computers into these groups in situations where that is helpful. In other words, we should move away from thinking about “putting humans in the loop” to “putting computers in the group.”

In, Superminds, Malone asks, “If businesses or other organizations want to use computers as part of human groups, what roles should computers play in those groups?” Thinking about the roles that people and machines play today, there are four obvious possibilities. People have the most control when machines act only as tools; and machines have successively more control as their roles expand to become assistants, peers, and, finally, managers. Let’s examine each of these roles”

A physical tool, like a hammer or a lawn mower, provides some capability that a human doesn’t have alone; but the human user is directly in control at all times, guiding its actions and monitoring its progress. Information tools are similar. When you use a spreadsheet, the program is doing what you tell it to do, which often increases your specialized intelligence for a task like financial analysis.

But many of the most important uses of automated tools in the future won’t be to increase individual users’ specialized intelligence, but to increase a group’s collective intelligence by helping people communicate more effectively with one another. Even today, computers are largely used as tools to enhance human communication. With email, mobile applications, the Web (in general,) and sites such as Facebook, Google, Wikipedia, Netflix, YouTube, and Twitter, we’ve created the most massively connected groups the world has ever known. In all these cases, computers are not doing much “intelligent” processing; they are primarily transferring information created by humans to other humans.

While we often overestimate the potential of AI, we often underestimate the potential power of this kind of hyper-connectivity among the 7 billion or so amazingly powerful information processors called human brains that are already on our planet.

Unlike a tool, a human assistant can work without direct attention and often takes the initiative in trying to achieve the general goals someone else has specified. Automated assistants are similar, but the boundary between tools and assistants is not always a sharp one. For instance, text-messaging platforms are mostly tools, but they sometimes take the initiative and autocorrect your spelling, occasionally with hilarious results.

Another example of an automated assistant is the software used by the online clothing retailer Stitch Fix Inc, to help its human stylists recommend items to customers. Stitch Fix customers fill out detailed questionnaires about their style, size, and price preferences, which are digested by machine-learning algorithms that select promising items of clothing.

The algorithmic assistant in this partnership is able to take into account far more information than human stylists can. For instance, jeans are often notoriously hard to fit, but the algorithms are able to select for each customer a variety of jeans that other customers with similar measurements decided to keep.

And it is the stylists who make the final selection of five items to send to the customer in each shipment. The human stylists are able to take into account information the Stitch Fix assistant hasn’t yet learned to deal with ? such as whether the customer wants an outfit for a baby shower or a business meeting. And, of course, they can relate to customers in a more personal way than the assistant does. Together, the combination of people and computers provides better service than either could alone.

Some of the most intriguing uses of computers involve roles in which they operate as human peers rather than assistants or tools, even in cases where there isn’t much actual artificial intelligence being used. For example, if you are a stock trader, you may already be transacting with an automated program-trading system without knowing it.

And if your job happened to be dealing with insurance claims for a New York City company called Lemonade Insurance Agency LLC, you already have an automated peer named “AI Jim.” AI Jim is a chatbot, and Lemonade’s customers file claims by exchanging text messages with it. If the claim meets certain parameters, AI Jim pays it automatically and almost instantly. If not, AI Jim refers the claim to one of its human peers, who completes the job.

What about the manager role? Human managers delegate tasks, give directions, evaluate work, and coordinate others’ efforts. Machines can do all these things, too, and when they do, they are performing as automated managers. Even though some people find the idea of a machine as a manager threatening, we already live with mechanical managers every day. A traffic light directs drivers; an automated call router delivers work to call center employees. And most people don’t find either situation threatening or problematic.

It’s likely that there will be many more examples of machines playing the roles of managers in the future. For instance, the CrowdForge system crowdsources complex tasks such as writing documents. In one experiment, the system used online workers (recruited via the Amazon Mechanical Turk online marketplace) to write encyclopedia articles. For each article, the system first asked an online worker to come up with an outline for the article. Then it asked other workers to find relevant facts for each section in the outline. Next, it asked still other workers to write coherent paragraphs using those facts. Finally, it assembled the paragraphs into a complete article. Interestingly, independent readers, on average, judged articles written in this manner to be better than articles written by a single person.

Now that we understand the roles machines can play, let’s examine the cognitive processes needed if you want to design a supermind (like a company or a team) that can act intelligently. Every mind, whether it is an individual or group needs to perform some or all of these five cognitive processes:

1. create possibilities for action,

2. decide which actions to take,

3. sense the external world,

4. remember the past, and

5. learn from experience.

Entities that act intelligently whether they are people, computers, or groups, need to do these things. As Malone observes, “computers can help do all these things in new ways that often, but not always, make the superminds smarter.”

He uses the example of strategic planning at a large consumer products company similar to P&G.

Today, corporate strategic planning in large companies usually involves a relatively small group of people, mostly senior executives, their staff, and perhaps some outside consultants. But what if we could use technology to involve far more people and let machines do some of the thinking?

Consider process #1: create possibilities for action.

As we discussed earlier, one of the most important roles for computers is as a communication tool that allows much larger groups of people to think together productively. A promising approach for doing that within the strategic planning process is to use a family of related online contests, called a contest web. https://sloanreview.mit.edu/article/how-human-computer-superminds-are-redefining-the-future-of-work/ - ref10 There could be separate online contests for strategies at different levels of the organization. For example, if P&G used this approach, the company might have separate contests for each brand, such as Pantene shampoo, Head & Shoulders shampoo, and Tide laundry detergent. It could also have separate contests for how to combine the strategies of the brands in each business unit, such as hair care and fabric care. And the company could have another contest aimed at combining the business unit strategies into an overall corporate strategy.

Each contest could be open to many company employees, perhaps all of them. Anyone in the contest could propose a strategic option, and others could comment on or help develop the idea. Eventually there would be one winning strategy chosen in each challenge, but during the planning process, it would be important to consider a number of different options.

Opening this process to lots of people could allow surprising new options to arise. For instance, a group of young, tech-savvy employees, who would never have been included in a traditional corporate strategic-planning process, might propose a new cosmetics concept involving skin and eye makeup specially formulated for individual customers who upload selfies to the website.

Consider process #2: decide which actions to take.

One benefit of involving more people in generating strategic possibilities is that you get far more possibilities. But deciding which possibilities are most promising requires evaluating them all, and new technologies also make it easier to involve far more people and more kinds of expertise in evaluation. For instance, P&G might want its manufacturing engineers to evaluate whether it is technically feasible to make a product, its operations managers to estimate manufacturing cost, and perhaps outside market researchers to predict the demand for the product at different price points.

In some cases, it may be worth combining many people’s opinions about some of these questions. For instance, P&G might use online prediction markets to estimate the demand for products. Such markets have already been used to successfully predict movie box-office receipts, winners of U.S. presidential elections, and many other things. Somewhat like futures markets, prediction markets let people buy and sell “shares” of predictions about future events. For instance, if you believe that global sales for Pantene shampoo will be between $1.8 billion and $1.9 billion per year, you could buy a share of this prediction. If the prediction is right, then you will get, say, $1 for each share you own of that prediction. But if your predictions are wrong, you will get nothing. That means the resulting price in the prediction market is essentially an estimate of the probability that sales will be in this range.
Next, consider process #3: sense the external world.

A key necessity for developing good strategic plans is the ability to effectively sense what is going on in the external world: What do customers want now? What are our competitors doing? What new technologies might change our industry? By far the most visible means for improving sensing today are big data and data analytics.

For example, P&G might analyze the positive and negative comments about its products in online social networks to gauge how customer sentiment about the products is changing. It might conduct online experiments at different prices for the products. And it might be able to obtain early warnings about sales changes by installing video and touch-sensitive floors in retail stores to analyze how much time customers spend looking at P&G’s products versus competitors’ products.

P&G might even be able to do something Amazon has already done: use vast amounts of data to develop detailed models of many parts of its business, such as customers’ responses to prices, ads, and recommendations, and sort out how supply-chain costs vary with inventory policies, delivery methods, and warehouse locations. With tools like these, computers can take over much of the quantitative work of strategic planning by running the numbers, and people can use their general intelligence to do more qualitative analysis.

Then, consider process #4: remember the past.

Another way technology can help superminds create better strategic plans is by helping them remember good ideas that others have had in similar situations. For example, software assistants embedded in an application for generating strategy proposals could automatically suggest generic strategies, such as the following:

- Integrating forward by taking on some of the tasks done by your customers, or integrating backward by taking on some of the tasks done by your suppliers;

- Outsourcing more of the things you do internally to freelancers or specialized providers;

- Moving into related market segments, nearby geographical regions, or other markets frequented by your customers. And,

- When you pick one of these options, the system could then automatically provide a template including the kinds of details necessary for that type of strategy.

By remembering good strategies from other settings, software assistants could help generate new strategies for your setting. For instance, if the strategy of using selfies to customize cosmetics was successful, a software assistant could suggest similar strategies that let customers use smartphones to customize P&G’s other products: shampoos, toothpastes, laundry detergents, potato chips, and others. Of course, many of these combinations would be silly or impractical and could be very quickly eliminated, but some might be surprisingly useful. And even silly options sometimes give rise to good ideas.

For instance, in the early 2000s, P&G developed a process for printing entertaining pictures and words on Pringles potato chips.https://sloanreview.mit.edu/article/how-human-computer-superminds-are-redefining-the-future-of-work/ - ref14 An approach like this might have led to another promising idea: using this technology to let customers buy Pringles that are preprinted with images that customers specify themselves.

Now, consider process #5: learn from experience.

If a system is used over time, it can help a supermind learn from its own experience to become more and more effective. For example, it might help recognize strategic ideas that most people wouldn’t recognize in their early stages. In the 1970s, when Steve Jobs and Bill Gates were first playing around with what we now call personal computers, most people had no idea that these strange, awkward devices would turn out to be among the most innovative and influential products of the next several decades.

It’s certainly not easy to rapidly filter ideas without missing these diamonds in the rough. But perhaps it’s possible to identify the unusual people who do have this skill by systematically tracking over time how accurately, and how early, people predict technological advances and other kinds of breakthroughs. Then, we could ask these people to take a second look at some of the “crazy” ideas that we might otherwise reject.

Another intriguing possibility is to use “learning loops” that begin with human experts evaluating strategies manually and then, gradually automate more and more of the work as the machines get better at predicting what human experts would do.

In a company such as P&G, which generally tries to compete on quality rather than price, experts evaluating product strategies usually reject those that emphasize competing on low price. But instead of programmers writing programs that explicitly filter out low-price strategies, a machine-learning program might recognize that experts often reject these types of strategies and start suggesting this action. If the experts agree with the suggestion enough times, then the program might stop asking and just do the filtering automatically.

Business strategy is just one of the myriad problems where smart machines will make existing superminds, as well as totally new ones outperform those composed only of humans. This will enable us to raise economic output at a much faster rate than today’s slow population growth would imply, without creating massive unemployment. The big challenge remains providing humans with the skills to take advantage of machine intelligence and building machines that can maximize human performance. In many cases, this will enable tomorrow’s superminds to routinely do things that have heretofore been impossible for any group of humans or machines.

Given this trend, we offer the following forecasts for your consideration.

First, by 2025, the kind of cyber-human business strategy supermind described earlier will be available as a service from one or more consulting firms.

Given how complex such a system could be and how generic much of the work would be, it’s unlikely that companies will develop proprietary systems for this purpose. Instead, today’s consulting firms, or their future competitors, will provide much of this functionality as a service. The firm will have a collection of people at many levels of expertise “on call” who could rapidly generate and evaluate various strategic possibilities, along with software to automate some parts of the process and help manage the rest. Such a “strategy machine” will use a supermind of people and computers to generate and evaluate millions of possible strategies for a single company. Over time, computers will come to do more and more of the work, but people will still be involved in key parts of the process. The product will be a handful of the most promising strategic options from which the human managers of the company will choose. And,

Second, human-computer superminds will be used to solve all kinds of difficult business and societal problems.

Computers will use their specialized intelligence to solve parts of the problem, people will use their general intelligence to do the rest, and computers will help engage and coordinate far larger groups of people than has ever been possible. Applications range from designs for new houses, smartphones, factories, cities, and educational systems, to formulating antiterrorism approaches and medical treatment plans. The possibilities are virtually unlimited.
