In 2013, Google updated the software to validate a user by analysing their clicking style in the "I'm not a robot" checkbox currently used across the internet.
If the click seemed dubious, a more elaborate test would be required to ensure the user was human.
The new version promises to remove the need for box-ticking entirely, by monitoring interaction with the website and any past data Google holds on the user.
While this will be a reason for celebration across the globe, it begs the question on how Google will continue to preserve history - as the tech giant used CAPTCHA to help digitalise decades of old texts that scanning programs struggle to decipher.
By getting internet users to decipher scanned texts mistranslated by auto-digitising programs, internet users digitised 20 years worth of New York Times back issues in months and within one year, the equivalent of 17,600 books had been decoded.
