The general idea behind human growth, as a species, is that we build upon knowledge of the people that came before us to become smarter with every passing generation. And, to some degree, this is true; we have, and we do, indeed use existing knowledge to innovate and create or find new things. However, there is some concern that technology may be “dumbing down” the average Joe…

…and there may be some truth behind it.
