I'm sure you've all run into the "Are you a computer question?" on Internet applications for e-mail accounts and social networking sites. Most of the time they don't bother me but every once in a while, I run into one that appears to be impossible. The letters are so squiggly and wiggling they’re hardly identifiable and they don't form an actual word. I see a time when computers will be so good at recognizing even terribly mutilated letters that the image presented will be unrecognizable for both humans and machines. At that point, no one will get new accounts.
