A captcha is difficult for most computers to solve because it distorts letters
and numbers in unusual ways, says Vicarious co-founder Scott Phoenix.
Humans use their powers of perception to see a "m and o" with a line through
it and still read the word "morning."
"We picked CAPTCHA to solve because it was explicitly designed to be
impossible for computers to solve. If you're trying to build artificial
intelligence, CAPTCHA a great test," Phoenix says.
