Quick Thoughts: Artificial intelligence—A Primer

What is artificial intelligence?

AI is defined in the Oxford English Dictionary as the “development of computer systems able to perform tasks normally requiring human intelligence.” However, that definition is sufficiently vague to encompass tasks that ordinary calculators have managed for several generations with the ability to add, subtract, multiply, or divide.

Therefore, what distinguishes AI from mere computing is the ability of computer systems to learn, adapt and hence acquire intelligence, which then allows them to respond dynamically to changing situations in ways that mimic and even exceed human ability. Or, as the father of the term AI, Professor John McCarthy of Stanford University put it in 1955, AI is “the science and engineering of intelligent machines.”

AI spans autonomous systems (e.g., robots that can self-navigate), machine learning (algorithmic pattern recognition based on large volumes of data), learning via labeling (using images to accelerate pattern recognition), and deep learning (e.g., using neural networks to draw inference, including from smaller samples).

Using AI, machines can now recognize voices and images, respond to spoken and written queries, best grandmasters in games such as chess and “Go,” and navigate complex and dynamically changing routes, among others.

While there is considerable debate about when AI was first “invented,” it is now old and advanced enough to be commonplace in many everyday usages, among them:

• E-commerce matching of consumers to goods and services (targeted marketing)
• Voice recognition assistants, such as Amazon’s Alexa or Apple’s Siri
• Fraud detection, above all in personal finance
• Filtering spam in email and other applications
• Facial recognition (replacing, for example, the need for passwords to enable smartphones, tablets, or computers)
• Navigation applications used in automobiles
• Robotic applications in healthcare, warehousing, and construction
• Diagnostic analysis, for example in radiology
• The development of autonomous (self-driving) vehicles, as well as auto safety features (e.g., automatic braking)
• Drafting documents (for example in marketing)

Artificial intelligence and the economics of innovation

Economists have long understood that sustainable increases in living standards require continuous innovations, ones that enable ongoing increases in output per hour worked (i.e., productivity). For most of human history, innovations either belonged to improvements in human capital (human know-how) or in physical capital (better tools with which to carry out tasks more efficiently).

AI, however, does not fit neatly into those distinctions. It may or may not improve human knowledge, skills or intelligence, and it may or may not provide workers with better tools to become more productive.

Instead, it may replace them.

Put differently, traditional innovations made existing workers more productive because they became “smarter,” gave them tools to produce more, or replaced humans with more productive machines.

But not all earlier innovations replaced workers.

For instance, the innovations of printing and much later, the internet, allowed workers to increase their skills and knowledge to become more productive. In pre-history, the taming of fire vastly improved human caloric input (in particular, of animal-based proteins), while the invention of the wheel enabled people and goods to be transported to where they were most needed.

From the end of the 19th century to the final decades of the 20th century, space and time shrank sharply owing to inventions that allowed instantaneous communications worldwide (e.g., the telegraph, telephone, and internet) and to innovations that compressed geography (e.g., the steamship, train, automobile, jet aircraft). Compressing distance in communications and transportation underpinned significant productivity gains associated with rapidly growing international trade and finance, which unleashed millions into the global labor force, many with much-improved jobs and incomes. Those gains, moreover, were distinctly positive sum.

Over the course of human history, therefore, productive innovations have both complemented human labor and replaced it. Fire, the wheel, and information were chiefly human-productivity-enhancing innovations. Other innovations, such as tractors, threshers, harvesters, and trucks replaced humans in agriculture. So did word processors and answering machines, which displaced secretaries and other administrative staff in the workplace.

One of the biggest emerging questions in economics, therefore, is whether AI will tend to be more of a complement or substitute to human inputs in production. In truth, no one yet knows, but perhaps for that reason, AI today is as much feared as it is admired.

The fear factor

The substitution of machines for human inputs has been a recurring theme of modern capitalism, beginning with the depopulation of agriculture in the United Kingdom and United States in the century between, roughly, 1850-1950. That was a period that saw over half of all Americans move from farming into industry and services, becoming uprooted from rural areas to urban and suburban ones. More recently, machines (including robots) have replaced workers in factories, resulting in large-scale declines in employment across many industries (most famously, along the automobile assembly line).

Captured in literature, movies and the arts, those vast dislocations, and the human pain and suffering they induced, are etched into the consciousness of peoples around the world. Modernity has always had a rough edge and has probably invited more trepidation than utopian dreaming over the several centuries of its existence.

It is therefore unsurprising that modernity’s latest incarnation—human-like machines powered by AI—strikes fear among much of the population.

But if history is our guide, it demonstrates that most innovations proceed apace, not respecting fear or tradition and that at best guardrails can be established to limit some of the innovations’ most nefarious impacts. Given the number of actors engaged worldwide in the development of AI and the fact, that by its nature, it can develop autonomously, it is difficult to see how it could be stopped, even if that were desirable (which it may not be).

Accordingly, the test will be whether institutions of human invention that establish the rules under which we co-exist—democracy and the rule of law chief among them—will have the durability and flexibility to establish the conditions under which AI improves the human condition, rather than harms it.

AI: How to invest in it

Innovation often evokes images of vast fortunes that are quickly made: Rockefellers and oil, Ford and automobiles, Gates and personal computers, Zuckerberg and social media. But while those narratives are demonstrably true, they also embed the notion of memory bias. History is written by and about the winners, with little space given to the losers.

Some of our readers may vaguely recall other once-famous names: Wang Computers, Pets.com, Netscape, or Friendster. Those are but a few in a long list of names in the age of the computer, the internet, and social media, that were once darlings of Wall Street, but subsequently fell flat on their faces.

There is a lesson in the juxtaposition of groundbreaking innovation that makes fortunes for some and footnotes for others, and it is that separating the two in real-time is difficult, if not impossible. It could be advisable to spread one’s investment capital across the sector, to capture the outsized potential returns of the theme, without unwarranted reliance on separating winners and losers before that is even possible.

At the same time, a deeper understanding of how broad themes can be applied to the security selection process and provide a larger potential for excess returns is needed, because these themes are often viewed as too difficult to measure. Thematic investing leaves space for more macroscopic decisions—those who can deeply understand a theme can potentially earn a larger alpha than has been earned recently through traditional active management.

In the analogy of baseball and statistics, scoring runs and winning games is about avoiding outs and advancing runners on offense, pitching and fielding well on defense. Teams with superstars don’t always or perhaps most often win pennants.

At least that is what ChatGPT told me.

WHAT ARE THE RISKS?

All investments involve risks, including possible loss of principal.

Equity securities are subject to price fluctuation and possible loss of principal.

Active management does not ensure gains or protect against market declines.

Investment strategies that incorporate the identification of thematic investment opportunities, and their performance, may be negatively impacted if the investment manager does not correctly identify such opportunities or if the theme develops in an unexpected manner.

Focusing investments in [consumer discretionary-, health care-, technology-, information technology-] related industries, carries much greater risks of adverse developments and price movements in such industries than a strategy that invests in a wider variety of industries.

To the extent a strategy focuses on particular countries, regions, industries, sectors, or types of investment from time to time, it may be subject to greater risks of adverse developments in such areas of focus than a strategy that invests in a wider variety of countries, regions, industries, sectors or investments.

Investments in fast-growing industries like the technology and healthcare sectors (which have historically been volatile) could result in increased price fluctuation, especially over the short term, due to the rapid pace of product change and development and changes in government regulation of companies emphasizing scientific or technological advancement or regulatory approval for new drugs and medical instruments.
