Today, we are launching an experiment to end this madness. We want to get rid of CAPTCHAs completely. The idea is rather simple: a real human should be able to touch or look at their device to prove they are human, without revealing their identity.
Their approach is interesting, though won’t be widespread until they can figure out additional ways to identify humans. Not everyone has a USB security key. But I’m hopeful they and others can end CAPTCHA.
