By Susan Kuchinskas
Luis von Ahn has heard it all before. As co-inventor of the CAPTCHA, those annoying images composed of wiggly letters and numbers that Web sites use to make sure you’re a human rather than a machine, von Ahn has received as many as 50 claims over the past decade of ways to beat his program.
Make that 51.

Vicarious's CAPTCHA-solving demonstration is an example of "narrow artificial intelligence," a technology that can match or even exceed human performance on a narrowly defined task. IBM's chess-playing Deep Blue is another such example. But Vicarious insists its computer perception software is the foundation of an AI that will learn the way humans do—by experiencing the world around it, principally via vision, and then identifying patterns. "If an algorithm solves vision in general, it is not narrow AI, it's a general AI system,” says, Dileep George, also a Vicarious co-founder. “We are working on a general algorithm for solving [the] vision problem, and CAPTCHA is a stepping stone to that.”

CAPTCHA inventor von Ahn, an associate professor of computer science at Carnegie Mellon University, doesn’t seem excessively worried. It is hard to determine exactly how much better Vicarious's technology is than other work in the field, he says. The Vicarious approach, which relies on visual perception, is in line with current thinking about AI, according to von Ahn. "Many artificial intelligence researchers spend most of their time dealing with perception,” he says. “It's believed that our own intelligence derives from our visual cortex.”
Even if it proves to be a technological dead end, "the one nice thing about the approach of using computer vision is that at the very least, it has applications," von Ahn notes. For example, technology based on Vicarious’s system might someday give a self-driving car the ability to identify pedestrians straying onto a roadway.
Those darn skeptical scientists can't see the brilliance.
