From the video, the `AreYouHuman' captcha strikes me as quite culture-specific. `Put the tools in toolbox', `make pancakes' -- some people will know what and how to, others will not. Meanwhile, a simple bot, as demonstrated, achieves high success rate. Could also be improved with automated learning , using suitable AI library; such libraries are freely available for making games. With both false negatives and false positives high, the captcha's either done for, or at least needs some serious tweaks.
