The future of OCR, and a poll policy

nancylebovOne of my commenters suggested that old books will never be properly OCRed because the pages are apt to be warped because of early paper-making.
I believe this is a temporary problem-- that degree of warping is just mild and fairly simple geometrical transformation.
If the usual captchas are useless, one solution is to go to simple semantic captchas. I've seen a few of those which require answering a very simple arithmetic problem or figuring that "What is the opposite of hot?" isn't a trick question.
Are there other possibilities? Will the reverse Turing test (machines recognizing people) continue to be reliably solvable?
There's a poll at my livejournal. Polls don't seem to get transferred with the automatic cross-post from dreamwidth, creating polls a second time by hand isn't my idea of fun, and most of my commenters are at livejournal.
