There seems to be no end to predictions of storm clouds when computers eventually decide to take matters into their own hands (or should we say, their own processors).
"The development of artificial intelligence could spell the end of the human race," Stephen Hawking warned.
"[AI] scares the hell out of me. It's capable of vastly more than almost anyone knows, and the rate of improvement is exponential," said OpenAI cofounder Elon Musk.
AI technologies present "profound risks to society and humanity," according to a letter signed earlier this year by more than 1,000 technology leaders urging a moratorium on AI research until more is understood about potential risks.
"We need to be very careful," said Yoshua Bengio, a professor and AI researcher at the University of Montreal.
While not disregarding the promise of tremendous good that AI will bring to a broad range of sectors in industry, economics, education, science, agriculture, medicine and research, media reports are increasingly sounding an alarm over the unintended consequences of this burgeoning disruptive technology.
One area of concern is emergent behavior, defined as a series of unanticipated, unprogrammed interactions within a system stemming from simpler programmed behaviors by individual parts.
Researchers say evidence of such behavior is seen in models that learn languages on their own, when systems trained to play chess and Go generate original strategies to advance, or when robots exhibit variability in motion patterns that were not originally programmed.
"Despite trying to expect surprises, I'm surprised at the things these models can do," said Google computer scientist Ethan Dyer, responding to an AI experiment in which a computer unexpectedly deduced on its own the title of a movie based on a string of emojis.
But Dyer himself may be surprised to learn that a research team at Stanford University is throwing cold water on reports of emergent behavior.
Ryan Schaeffer, Brando Miranda and Sanmi Koyejo said in a paper posted last week that evidence for emergent behaviors is based on statistics that likely were misinterpreted.
"Our message is that previously claimed emergent abilities … might likely be a mirage induced by researcher analyses," they said.
