How close, if at all, are computers to solving captchas?

It's pretty hard to solve captchas in general the way the human brain does it (hell, with some captchas even we humans sometimes have our troubles). However, for a specific kind of captcha, it's mostly pretty easy to create a solver program - this is what is done when bot runners for some reason want to spam or hack a given site. Solving simple captchas is an exercise often used in machine learning and artificial intelligence classes, since basic pattern recognition algorithms can be easily applied and demonstrated on the problem.
