I was a robot four times out of five. This sheds a new light on my existence.

On a serious tone, apart from a cool showcase of technology, do we REALLY need this? CAPTCHAs are the bane of everyone's internet time. Sometimes it works, sometimes it doesn't, sometimes I have to write strange unicode letters, when it fails I have to go back and re-input everything in the form,... And more importantly, the persons it's supposed to prevent from abusing a service are not likely to be stopped by these childish "anti-bot measures".
