Fun fact: Every time you fill out one of these Google Captcha's you're slightly training an A.I. A.I. systems for self driving or identifying objects need massive amounts of human labelling to learn from, and you're labelling these 9 pics as either: - It's a car - It's not a car The A.I. system then shows these same pics to many other humans (sorry you're not that special 😛), and then determines if it was correct or incorrect about labelling the images. ...and that's how it learns and gets better. Neat huh!
