I've always felt that it would be only a matter of time before computer vision would be able to solve the (re)CAPTCHA problem. Especially since digit classifiers are able to match the performance of humans.
One approach that I enjoyed seeing was the use of reverse captchas. Here you pose a problem that a computer can easily solve, but a human cannot. For instance, if you ask a simple question (1+1=?), but you place the question box off the screen so the user can't see it. A computer would be able to easily answer the question, but a human user would have no way of doing so.
