This was literally a homework assignment in a security course I took during undergrad so excuse me if I'm not impressed. Also, from the comments it's clear that the benefits of Captchas are being overlooked. Google purchased ReCaptcha some time ago and uses it to solve difficult OCR problems by using human input. In Recaptcha you'll notice that there are always two words, and one tends to be easier than the other. The one that is easier has a known result and is used for security, the other one is unknown and Google will use people's guesses to find its true result. Even if this startup was to consistently solve the hardest Captchas on the internet, it would actually be a good thing because we would have better OCR. Realistically this won't happen and ReCaptcha will just use harder images all the time if it needs to.
