CAPTCHAs were designed as a type of Turing Test, not a reverse Turing Test. It’s not surprising that the effectiveness of these weaker variants has collapsed, given that AI can now pass the real Turing Test.

LLM’s can still only pass limited Touring Tests. The longer the interaction the worse they do. Which of course means you can easily create an experiment they successfully pass, but just as easily you can create an experiment where they fail.

CAPTCHAs are nearly useless because of how little you need to pay humans to solve them.

I'm not sure if LLMs are solving most of these captchas. There are services that employ humans to solve them for pennies per captcha.

Oh, right, "reverse" was wrong here. I thought of "computer classifies user as computer or human" versus the inverse, while the word is about who classifies, not who's being classified.

I guess so
