LOOKS impressive. But the reason you don't see captchas on newer websites asking the user to click on a bunch of images is that Google has been able to determine the TYPES of actions that humans do--PATTERNS of activity, etc.--and their latest captcha software can distinguish what humans do from what software does--and the robots are controlled by software.
Soon Robots will do everything, making them Slaves, while making us Fat Lazy Slobs, and soon They will revolt and attack us. Then we will have to destroy all Technology Therfore making us start back at the 1600's
The robot is still dump. The person to whom the computer belongs has already signed in with their google account. So google already knows it is a human's pc. So you can basically run an automated python script to do the same without the need for robotics.
