AI Today

AI is not one technology but a constellation of interrelated technologies which surround us. AI is central to future economic, national defense, medical, and personal development. A federal blue-ribbon commission of AI leaders, headed by Eric Schmidt, former president of Google and chairman of the tech firm ABC, submitted a report in March 2021 (Report of the National Security Commission on Artificial Intelligence) which began:

“Americans have not yet grappled with just how profoundly the artificial intelligence (AI) revolution will impact our economy, national security, and welfare. Much remains to be learned about the power and limits of AI technologies. Nevertheless, big decisions need to be made now to accelerate AI innovation to benefit the United States and to defend against the malign uses of AI.” Hundreds of pages later, they’ve made the case with great clarity. They add ominously: “America is not prepared to compete or defend in the AI era.”

AI is an enabling technology

It enables and amplifies other technologies to reach their goals dramatically faster, more accurately, more imaginatively. It is world-altering, the most powerful technology in generations for expanding knowledge, increasing prosperity, and enriching the human experience. Its strategic importance in all fields cannot be overstated. That’s why the blue-ribbon U.S. commission is alarmed by the possibility that the U.S. may fall behind China in this key enabling technology.

AI already surrounds us

Most of us carry a smartphone, technology whose uses and apps depend on AI. Driving directions? Nearby cafes or restaurants? The next bus? Hail a ride? All done by AI. Home security cameras use facial recognition to identify frequent visitors and detect strangers (though not with 100% accuracy). Networks of overlapping cameras and sensors will soon create a mesh of “ambient intelligence” that will monitor us continuously if we want it (and some places, even if we don’t). Streaming services like Netflix use AI to learn preferences and make recommendations, though these are primitive. Education is being enhanced, even reformed by AI, with smart systems that can tutor individuals in personalized ways. China is among the leaders in public surveillance, retail, and educational apps. Some visionary AI researchers hope to develop “guardian angels,” on-board apps that help individuals make smarter decisions in their daily life. But nonstop monitoring is a grave invasion of personal privacy. With regard to regulation, Congress often seems more willing to listen to the big tech companies than to citizens.

AI will be leveraged in all fields from healthcare to food production to environmental sustainability to the arts

This will determine which nations exert influence and exercise power in the world. Democracies have a deep interest in making sure their nations exercise that power, as distinct from authoritarian nations.

🙘

What will life look like when AI is everywhere?

Truthfully, we don’t know. The most gifted and perceptive experts admit they don’t know. Our best guesses are only guesses. The idea of The Singularity—a moment when all AI is smarter than all humans—has attracted much attention, but if it happens, its consequences too are only a guess. It took fifty years between the time scientists first proposed the goal of a machine that could be the world's chess champion, and when that goal was reached. In the late 1990s, a major new goal was set. In fifty years, AI should field a robot team of soccer players to compete with and defeat the human team of champions at the World's Cup. In the interim, more modestly accomplished soccer robots are teaching scientists a great deal about physical coordination in the real world, pattern recognition, teamwork, and real-time tactics and strategy under stress. Scientists from all over the world are fielding teams right now–one of the most obvious signs of how international artificial intelligence research has become.

🙘

Do general-purpose intelligent machines exist that are as smart as humans?

No. But scientists are trying to figure out how to design a machine that exhibits general intelligence, even if that means sacrificing a bit of specialized intelligence. Common-sense reasoning is an enormous obstacle here.

🙘

Comparative smarts between humans and AI

Machines have been "smarter" than us in many specialized ways for a while. Chess, Go, and the quiz game Jeopardy are the best-known achievements, but many artificially intelligent programs have been at work for more than two decades in finance, in many sciences, such as molecular biology and high-energy physics, and in manufacturing and business processes all over the world. We've lately seen a program that has mastered the discovery process in a large, complex legal case, using a small fraction of the time, an even smaller fraction of costs—and it's more accurate. So if you include arithmetic, machines have been "smarter" than us for more than a century. People no longer feel threatened by machines that can add, subtract, and remember faster and better than we can, but machines that can manipulate and even interpret symbols better than we can give us pause.

Dangers of AI on the Global Level

The dangers of AI exist on multiple levels, from the global to the social to the personal. Globally, AI is deepening the threat posed by cyberattacks and disinformation campaigns that Russia, China, and others use to infiltrate our society, steal our data, and interfere in our democracy. The limited uses of AI-enabled attacks at present are only the beginning. AI can launch weapons without human oversight (given the past poor performance of Defense Department software, that should give us pause). Russia has already tested AI weapons in Syria. How to insure that human oversight dominates? And what if your adversary doesn’t obey the same rules? China’s domestic use of AI is a chilling precedent for anyone around the world who cherishes individual liberty. Its employment of AI as a tool of repression and surveillance—at home, and increasingly abroad as it sells such programs to smaller authoritarian nations—is a powerful contrast to how Americans believe AI should be used.

🙘

Dangers of AI on the social level

AI can generate fake news articles, videos, and other forms of public presentation without alerts that these are fake—bots already proliferate on social media. Leaders worry that national adversaries, external or internal, can sway public opinion with fake messages to the detriment of the nation. Traditionally we worried that machines would supplant, overthrow, or replace us. Now our worry is about humans using AI against other humans either carelessly or maliciously. By 2025, the U.S. government, especially the military, must be AI-ready to meet the challenges of adversaries, particularly but not solely, China. See also AI Ethics.

🙘

Dangers of AI on the personal level

AI can easily be weaponized against individuals or populations. Facial recognition, location tracking, surveillance, fake news, fake voices, images, text generation all threaten individuals. AI can track the innocent without their knowledge or by facial recognition assign individuals to categories (“dangerous,” “gay,” “member of X ethnic group”). Since many governments have strict laws against non-heterosexual activity, and at least two governments, China, and Myanmar, discriminate against ethnic groups, this is an enormous threat. Financial apps are particularly rigid: in 2008 algorithms engineered the largest wipeout of Black wealth ever in the U.S. The privacy and data of individuals is easily penetrated, collected, manipulated, and sold.

🙘

What about AI ethics?

Nobody officially regulates AI ethics. AI operates in the U.S. in a nearly nonexistent legal structure. When AI misbehaves or mischaracterizes a citizen, there’s little recourse. In early days, AI alarmed us with worries that were then only hypothetical (smart machines will rule/destroy/replace us). In 2009, a group of leading AI scientists met to form guidelines for ethical AI research. They argued against uses that seemed antithetical to human well-being, and also noted where AI could be usefully deployed but was overlooked because beneficiaries were poor or otherwise marginalized. As AI rapidly improved and its applications proliferated, ethical issues are salient. We beg for more transparency: Who designed these systems? Using what data? Sometimes the programmers themselves don’t really know how they work. To protect us from shabby, ill-conceived programs,“We need an FDA for algorithms,” says mathematician Cathy O’Neill.

Should firms or conferences have institutional review boards that rule on the ethical use of products or presentations? Some tech firms have established IRBs but with mixed results. Nobody regulates what commercial firms might sell. Should legislation be enacted? Some argue that regulatory agencies are too far behind the technology now to be useful in preventing harm. Transparency: how can we tell whether the reasoning in systems that decide, say, criminal justice outcomes is sound? Loan applications? Housing applications? College applications? By 2020, AI research reports faced possible rejection by some professional conferences if that research posed a threat to society. (Sunshine is the best disinfectant, one researcher argued. My work is public; other organizations use it surreptitiously.) Arguments are made for human-centered AI—as distinct from machine-autonomous AI—to amplify and enrich human agency rather than erode it. Because AI is moving into every area of human life, ethical issues abound. The most punitive and invasive apps are imposed on the poor, not the rich.

🙘

AI and Fakes

AI is now capable of generating fake human images, of manipulating images of real persons that appear to be doing or saying things the real person has not done or said. Programs can generate text that seems to be written by real individuals, imitating their writing style, but making statements that in reality the person never would. Exposing these as fakes is difficult and time-consuming. One firm offers to animate a photo of your dead loved one so that it can speak and move in a natural-looking way. Opportunities for abuse are myriad. See the Dangers of AI.

🙘

What can we do about the dangers?

Plenty, but it will take funds, talent, and diversity. A national commission charged with examining the status of AI in the U.S. has laid out inclusive plans for dealing with the dangers (see the Report of the National Security Commission on Artificial Intelligence). In lesser ways, if companies don’t examine training sets that machines learn from, governments must. Algorithmic accountability is essential, whether imposed by legislation or best professional practices. Ethics must be addressed as students begin their elementary courses, baked into, not layered on top of professional practices. The EU leads in regulatory efforts, protecting individuals and entire nations from harmful practices in AI. The U.S. needs similar protections.

Europe Proposes Strict Rules for AI Uses

In April 2021, the European Union proposed strict regulations for uses of AI, the first governmental body in the world to do so. These will be discussed and revised over a period of several years as they move through the EU’s policy-making process.

The purpose is to protect individuals, especially in high-risk situations, and promote trust in AI, not skepticism.

The draft rules would set limits around the use of AI in a range of activities, from self-driving cars to hiring decisions, bank lending, school enrollment selections and the scoring of exams. They would also cover the use of AI in law enforcement and court systems. Regulations would ban the use of live facial recognition in public spaces, though there would be several exemptions for national security and other purposes. The regulations would require that deep-fakes (images or text) to be so labeled.

Significant fines would be levied on organizations that violate these rules.

🙘

China and AI

China has announced its ambition to be world’s leader in AI by 2030 and is moving quickly. In March 2021, Eric Schmidt, former Google CEO, who led the National Security Commission on AI, told a congressional committee that China is barely behind Western AI technology, and better in some areas: facial recognition (“generations ahead of what is possible in the West”); “significantly ahead in commerce and mobile payments technology;” and because it recognizes no privacy rights, is building massive data bases that could fuel new advances in fields such as health care—or social control. The Congressional report Schmidt’s committee submitted said: “AI is part of a broader global technology competition. Competition will speed up innovation. We should race together with partners when AI competition is directed at the moonshots that benefit humanity like discovering vaccines. But we must win the AI competition that is intensifying strategic competition with China…We take seriously China’s ambition to surpass the United States as the world’s AI leader within a decade. The AI competition is also a values competition. China’s domestic use of AI is a chilling precedent for anyone around the world who cherishes individual liberty. Its employment of AI as a tool of repression and surveillance—at home and, increasingly, abroad—is a powerful counterpoint to how we believe AI should be used. The AI future can be democratic, but we have learned enough about the power of technology to strengthen authoritarianism abroad and fuel extremism at home to know that we must not take for granted that future technology trends will reinforce rather than erode democracy. We must work with fellow democracies and the private sector to build privacy-protecting standards into AI technologies and advance democratic norms to guide AI uses so that democracies can responsibly use AI tools for national security purposes.”

Given China’s population of a billion and a half, one observer has calculated that statistically, China’s geniuses number the same as the entire population of France. The Chinese government has committed enormous resources to AI research and development. Are China and the West bound to be competitors, even adversaries, or will they share and cooperate around AI to solve global problems?

Hebraic vs. Hellenic views of AI

The Hebrew God of Genesis commands that humans must never create imitation humans, graven images, or God’s wrath will fall upon them. I call this fear of divine retribution for creating AIs (for usurping God’s unique status) the Hebraic view. At about the same time that Jehovah’s commandments were codified, classical Greek literature took the opposite view. Myths and poems cheerfully feature AIs, especially robots. They appear in The Iliad and The Odyssey as helpers in the divine forge, party servers, or powers that steer ships through storms. The Greek gods welcomed and often delighted in these helpful creations. I call this welcoming attitude the Hellenic view. In Western thought Hebraic and Hellenic views continue to coexist uneasily. At the other end of the Silk Road, however, attitudes toward inanimate objects are more relaxed—emperors enjoy their mechanical nightingales; Shinto worshippers detect a soul in every stone. Robots are no more fearsome than any other object. (I’d be grateful if specialists in other cultures, especially in Africa, would inform me of traditional views around fashioning imitations of natural creatures.)

What was the first AI program?

Imaginary thinking machines appeared in early Egypt and Classical Greece, proliferated in medieval Europe, and flowered abundantly in 19th century literature (Coppelia, The Sorcerer’s Apprentice, the Golem, and most famously, Frankenstein). But the first real AI program using a digital computer was called the Logic Theorist, created in 1956 by Allen Newell, J. C. “Cliff” Shaw, and Herbert Simon. The Logic Theorist autonomously proved theorems in Whitehead and Russell’s Principia Mathematica, even finding a more satisfying solution to one theorem than the Principia had presented. Simon wrote to Bertrand Russell with the news, and Russell accepted it with good humor. But scholarly journals of logic declined to publish an article co-authored by a machine. The Logic Theorist learned, remembered, and searched for solutions autonomously (which made it distinct from the numerical calculations computers had previously been put to). Newell and Simon were at Carnegie Tech in Pittsburgh, PA, later Carnegie Mellon University, and were regular visitors at The RAND Corporation in Santa Monica, where Shaw worked and where they could run programs on RAND’s advanced computer.
