Smart Machines and Artificial Intelligence

By Donald Christiansen

I started this column with the intention of discussing artificial intelligence (AI). But not everyone seems comfortable with the term. Machine intelligence may be a better description. Machine intelligence has been with us since long before the term artificial intelligence was coined in the 1950s. It played a rudimentary role in early motorized machine tools, which skilled technicians designed and programmed to do more and more of what human operators had once been required to do.

Stanford computer science professor Fei-Fei Li points out there is nothing artificial about AI, noting that it is made by humans, is intended to behave like humans, and it affects humans. Then too, “artificial” often carries the connotation of inferior or not genuine. Yet its defenders respond by asking whether most things made by humans aren’t artificial in some sense.

These arguments notwithstanding, I will defer to the description “AI” for the balance of this column.

AI can be employed in solving complex mathematical problems, to which, of course, there is but one correct solution. Or it can be applied to complex situations having many variables, some or all of which may change with time. An example would be evaluating the status of an offensive or defensive military situation. It is in evaluating real-life situations that AI faces its greatest challenges, including financial, legal, ethical, and moral issues.

How Intelligent?

Since AI is designed by humans, the question arises, how intelligent must the human (or humans) who design a particular AI system be? And, given the same project, two separate groups of human intellectuals may reach opposite conclusions. Which group’s “brains” should be used to design an AI program? Suppose both designs are completed, one for a peaceful democracy and one for a warring dictatorship?

The answers to these questions are critical when dealing with potentially autonomous military systems. If and when such systems are permitted to operate in a fully autonomous mode is a major concern. The IEEE Global Initiative on Ethics of Autonomous and Intelligent Systems identifies several. Among them:

Defining Today’s AI

As the experts debate the definition and structure of AI, a criticism of its “deep learning” function has arisen. Deep learning is based fundamentally on statistical data processing, and its critics worry that it cannot intuit much from the vast amounts of data it collects. One response is a program proposed by the Pentagon’s DARPA. Called Machine Common Sense, it would provide a network to share technology ideas that emulate human common-sense reasoning, an area where deep learning is limited. Generally termed cognitive computing, another form is the intelligent virtual assistant (IVA) that helps retrieve answers to questions relating to specific, bounded procedures in a particular category.

Projecting the Future

AI today is still thought to be in its “weak” phase. Max Tegmark, president of the Future of Life Institute, cites AI driving a car as an example of weak AI. “Strong” or “superintelligent” AI, if it ever arrives, suggests that an AI system then becomes better than humans at all cognitive tasks. Such a system, Tegmark notes, could potentially undergo self-recursive improvement, triggering an intelligence explosion (and) leaving human intellect far behind.

Many students of AI are certain of the eventual development of superintelligent AI. What then? Some see it as the ultimate in salvation of the universe, while others fear it as devious, dangerous, and uncontrollable by humans.

Stephen Hawking in a 2016 speech at Cambridge University concluded that “AI will either be the best or the worst thing ever to happen to humanity. We do not yet know which.” On the positive side he listed the eradication of disease and poverty, and the repair of some of the damage done to the world by its industrialization. But he noted the dangers included powerful autonomous weapons, new ways for the few to oppress the many, and great disruption of the economy.

Even with today’s AI there are serious issues of concern, including the potential role of AI in cyber-security attacks on the U.S. electric grid system as well as similar attacks on the nation’s investment and banking structures.

But with respect to superintelligent AI itself running the world, not to worry! If it happens, it will positively not happen in our lifetimes. (A confidential AI source assured me of this.)
