Erm, see this from last week: http://www.scmagazine.com/security-researchers-defeat-recaptcha/article/488236/
"The researchers said the system they had devised was “extremely effective”, automatically solving 70.78 percent of the image reCaptcha challenges, while requiring only 19 seconds per challenge."
