[nfbcs] Captcha

[Gary Wunder]

To understand the problem of detecting whether or not you have a human or a
machine on the other end of the connection, consider SIRI. I can ask it to
add two numbers and it will. I can say "What day is it" or "What day of the
week is it" or "what day will it be tomorrow" If I come up with syntax it
does not understand, I am confident someone on the development team is
looking at this as well. We are fighting the problem of defining the
difference between artificial intelligence and human intelligence, and I
fear the only real difference is experience and there's lots of effort to
give machines that experience--language syntax, geographical information,
historical information, current news. What is it that makes us unique? If we
can't find that, then we will fail at coming up with a way to differentiate
between man and machine. Like John and Mike, I am not optimistic that we
will find a good captcha, so we have to continue to make our needs known and
not be left out.
