@shilolo – I think can follow the logic of your approach, but using the example and your split into a main question and a detailed part, the thought-provoking main aspect will very likely not be seen by many users. They will see
“How sophisticated will the processing power be of computers in 2015?”
and many (including myself) might not click on the question to answer it. The exciting part is related to the automatic recognition of Captcha character patterns (an artificial intelligence question like the Turing Test).
A Captcha is a type of challenge-response test used in computing to ensure that the response is not generated by a computer. The process usually involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. Thus, it is sometimes described as a reverse Turing test, because it is administered by a machine and targeted to a human, in contrast to the standard Turing test that is typically administered by a human and targeted to a machine. A common type of CAPTCHA requires that the user type letters or digits from a distorted image that appears on the screen.
