Your comment hints at recent AI developments, and it got me thinking, what is it that AI simply CANNOT do? Hands, it can't recognize them properly, even the times where it gets it close, it's still off.

Now, I'm not suggesting (NECESSARILY), that we create a captcha based on selecting the hands which are anatomically incorrect, but that there's these various blind spots where a human being is readily able to tell when a picture is of a real life object (or at least accurately modeled), and either mush turned out by a computer, or something which somewhat resembles the target, yet exhibits striking errors.

I'm not sure if there's any easy way to implement this, but it seems like if it could, it would be the next step in the bot arms race. Perhaps it'll stop working one day, but even if it just kills bots for a decade, it could be worth it.
