Captchas, the tests designed to differentiate humans from bots, are becoming more challenging as AI bots become more sophisticated. Researchers have found that bots can now solve distorted text Captchas with almost 100% accuracy, leading to the development of new types of Captchas that require users to perform tasks such as identifying objects, matching shapes, or moving a hand in the same direction as an object. Despite these efforts, bots continue to evolve, and the increasing difficulty of Captchas could have implications for access to online resources and services.
