The bottom line - is text based CAPTCHA dead? It’s definitely in pain thanks to evil marketers recruiting low-waged Indian data processing workers, who according to some of the statistics obtained, earn over ten times more while solving CAPTCHAs, than through their legitimate data processing jobs.

But what will replace it? What can replace it that doesn't have the same problems?
