I, like most SE users, am occasionally presented with a CAPTCHA to prove I'm human for one of any number of reasons. At the time of this writing there are 247 questions and 342 answers on Meta regarding CAPTCHAs and such questions often appear on the Community Bulletin (one appeared today which is what prompted this request). If I could search by emotion, I'm guessing the majority would be tagged angry.
On Monday, Google announced that an algorithm they have developed can solve reCAPTCHA with a 99.8% success rate. Searching around for studies indicating human solve success rate all indicate percentages less than that (for audio CAPTCHAs much less than that). This is no longer a valid method for determining if a user is human.
The answer to the highest rated Meta question on CAPTCHAs indicated that the SE staff were "heavily discussing this issue" and "agree that the current state of affairs sucks big-time" back in August 2012. Considering the advancement of a computer's ability to solve CAPTCHAs since then, I think it's about time for an alternative.
I'm not claiming to have a definitive answer but suggestions are, of course, welcome.
And I understand that polishing the meta split is probably priority right now, but can we at least get this on the docket?
