I'm not convinced that picking the pictures has anything to do with actually convincing google if you're a bot or not. I mean sure, it's an indicator. But I _know_ that I can pick the right pictures of school buses and store fronts every freaking time, so that's only a very small indicator. More likely, the majority of the algorithm is devoted to the "fingerprint" of your browser. If you have adblock running, you may not have a google ad cookie. If you have a randomizing user-agent addon, you're going to get blocked. What we need, for captcha, is an addon that makes you look as human as possible. Mouse click timings become random. Javascript fingerprint becomes John Smith common. Third party cookies, temporarily enabled (and then pruned). VPN traffic routed through a common looking gateway that few bots use. etc. etc.

You're assuming that the picking-of-pictures validation logic cares solely about what pictures you pick. What if it cares about your "mouse click timings" not being random, but rather looking like the mouse movements of a human who is using eye saccades to examine and classify images, and then moves their mouse only when they see and find one, and sloppily at that?

  Right, that's what I'm saying. I was putting forth that humans are pretty random with their timings. But the truth is, they are probably not and that we all probably click in some uniform distribution. But I am pretty sure, if you click on the images too quickly, you're going to get stopped. Slowing down your clicks, moving around a little like you're "thinking" seems to help. That's been my experience at least. I'm personally rooting for the AI here. When the robots and crawlers become so smart to become too hard for Google to distinguish between them and humans, then we will all benefit. They are becoming smarter, which is why captchas are becoming more difficult for humans.

My theory is that the challenges are actually just to slow down humans trying to do repetitive sensitive tasks (sign ups for instance).
