You may very well be correct. I've often said that anything a
computer can generate another computer can interpret. However, there
are differences between the two technologies with respect to timing
(a technology lag) and cost. If one develops a better captcha, there
will be a lag time between it's introduction and spammer's catch-up.
Also, what's the cost involved between development of the captcha as
compared to cost for it's solution? If the cost for development is
less then it may simply cost the spammer too much to keep up.
On these two points, I have to say it's possible to develop a captcha
that will work. However, that isn't saying that the captcha will be
accessible to all.
We may find ourselves at a point of asking the disabled (or anyone)
to take an alternate path for contributing. Such as, sending an email
asking for a password allowing them to contribute to a blog for
example.
However, a spammer could do the same. But, if you pass all requesting
emails through a spam filter, like spamcop.net, then that should
reduce spam to an acceptable level.
Perhaps I don't fully understand the problem, but there are many
things here to consider before giving up.
