Her/TerminatorWhich will it be?When artificial intelligence is as smart as humans, the world will change forever.
While technological change itself is neutral, neither good nor bad, AI's effects on society will be so powerful that they've been described in both utopian and apocalyptic terms.
And some futurists think those changes are just on the horizon.
That includes Ray Kurzweil - author of five books on AI, including the recent best seller "How to Create a Mind," and founder of the futurist organization the Singularity University. He is currently working with Google to build more machine intelligence into their products.
AI: Coming Soon
In an article he wrote for Time Magazine, Kurzweil says that even though most of the people in the field think we're still several decades away from creating a human level intelligence, he puts the date at 2029 - less than 15 years away.
Kurzweil argues we are already a human-machine civilization. We already use lower level AI technology to diagnose disease, provide education, and develop new technologies.
"A kid in Africa with a smartphone has more intelligent access to knowledge than the President of the United States had 20 years ago," he writes.
Continued development of AI technology could better provide information and solutions to each individual person on the planet - it could potentially be the thing that designs cancer cures and medications that stop cognitive decline.
Something To Fear?
While Kurzweil thinks the development of human-level AI can happen safely - after all, so far this more informed world hasn't turned on us - not everyone is so sure.
Elon Musk said AI could be the human race's "biggest existential threat" at a recent symposium at MIT. "With artificial intelligence we're summoning the demon," Musk said.
Stephen Hawking agrees. "The development of artificial intelligence could spell the end of the human race," he recently told the BBC.
They fear - as has been theorized by
So if that new intelligence doesn't like us or thinks we're harmful, it could decide to eliminate us. This wouldn't necessarily be the case, but if it was we probably couldn't stop it.
Of course, in the end, what Kurzweil estimates will happen in 2029 is the creation of a human-level intelligence, which isn't necessarily capable of becoming a force that takes over the world for good or ill.
But as Nick Bostrom, futurist and author of a recent book on AI titled Superintelligence, notes, just a little bit past the creation of a human level intelligence "is superhuman-level machine intelligence." Perhaps a machine with supercomputing processing power and human ability could even upgrade itself in short period of time.
"The train might not pause or even decelerate at Humanville Station," writes Bostrom. "It is likely to swoosh right by."
But Kurzweil argues that we've created other things that have the potential to destroy the human race with nuclear power and biotechnology and not only are we still here, we're actually living in the most peaceful time in human history.
He thinks that instead of viewing this creation as leading to a potential battle between humanity and a malevolent AI like Skynet, we should view it as something that has the power to elevate humanity, something that will exist in many forms, not just one all-powerful entity.
Avoiding The Robot Apocalypse
Kurzweil thinks we have time now to develop safeguards and to continue to establish a more peaceful and progress-oriented society, which could lead us to develop AI with the same goals, instead of (for example) a militaristic intelligence.
The best thing we can do to avoid a future peril, then, is simply to focus on our own social ideals and human progress - that and carefully build safeguards into the technology as we go.
That's more comforting than the potentially apocalyptic concerns of Musk and Hawking, though even Kurzweil writes that "technology has always been a double-edged sword, since fire kept us warm but also burned down our villages."
And we don't know if Kurzweil's prediction for human-level AI in 2029 will even come to pass.
Bostrom says that most prognosticators have predicted for years that a true AI is just "a couple of decades away," a sweet spot that's far enough to allow for necessary technological innovation but close enough to account for the fact that we think it's coming soon. But really, as he says, we just can't know the date that we'll all of a sudden understand intelligence well enough to re-create and even surpass it.
But we do know one thing, as Bostrom writes in his book: "We will only get once chance."
