Did you use early Google applications? Then the CAPTCHA isn’t something that’s too strange to you, and though I have personally hated it while using blogger, it happens to be an evil we can’t run away from—a necessary evil.
It was necessary to sift armies of robots from humans back then, but it has now gradually grown irrelevant as there are robots that master the texts faster, easier and better than humans, little wonder Google has finally decided to ditch it. And it looks like you won’t have to input anything at all starting now.
Well, before you jump off your seat and applaud the fact that you won’t be seeing CAPTCHA’s, I feel you should know that there will now be invisible CAPTCHA’s. Well, invisible CAPTCHA’s are the latest coming from the “Completely Automated Public Turing Test to Tell Computers and Humans Apart.”
Google updated reCaptcha which it got in 2009 to allow anyone just click on the “I am not a robot” checkbox which has now gone all over the internet. The search giant could easily tell when the click wasn’t human; when a click seemed fishy, a much more detailed test will then have to be carried out.
