A new type of neural network has cracked CAPTCHAs

It is with a heavy heart that I must tell you that an artificial intelligence has finally cracked a widely used tool that was literally made to differentiate humans from robots: the CAPTCHA.

CAPTCHAs are the annoying puzzles that might ask you to rewrite a piece of distorted text or click on all the automobiles in a photograph to log on to sites like PayPal. According to research published today in Science, a new type of AI was able to solve certain types of CAPTCHA with up to 66.6 percent accuracy. 

To put this in perspective, humans can solve the same type of CAPTCHA with about 87 percent accuracy due to multiple interpretations of some examples and a CAPTCHA is considered broken if a bot can pass it 1 percent of the time.

Erm... Yesterday I posted this
Today we have a neural network with an accuracy of 66.6%.
Oh dear...
