I'm not saying that the guy we watched on those videos was a genius, but his ideas were basically perfect. After being smart enough to invent the CAPTCHA concept, he then realized how its increased security functionality was also wasting a lot of time due to its prevalence across the internet. His devising this way to have people subconsciously help digitize books through doing what they're already doing- and I emphasize for free- is nothing short of amazing.
He also came up with several other games for helping people translate books as they learn effectively how to speak another language is mutually beneficial to both the company and the willing users who save money on expensive alternative computer language programs.
