Of Turing Tests and CAPTCHAs


(via WikimediaCommons)

 I've never been a fan of the so-called 'Turing Test.' This io9 article from George Dvorsky explains some of the problems with it, while offering up some possible alternatives:

It also interestingly notes that we already have today a sort of 'reverse Turing test' wherein a machine must detect if a person is a real human or not via those ubiquitous "CAPTCHA" verification challenges -- all of which results in an 'arms-race' of bot-makers trying to defeat the CAPTCHAs, and other humans trying to stay a step ahead of the bot-makers.

On a side-note, if you've never heard this explanation of CAPTCHAs (and the positive, creative use they're put to), from their creator, it's definitely worth a listen:
