Just found a wonderful resource regarding medieval history, Got Medieval, it's wonderful, check out this post for instance, on the Tyranny of the Scribe, where he discusses the stupidity of quotes like this one from Douglas Rushkoff:

"[These] are the stages that our civilization has moved through in successive stages of media. We went from people who just lived in a world that had rules that we don't even know what they are. Maybe it's going to rain, maybe it's not. Maybe if I sacrifice my kid to Moloch I'll get some plants this year, maybe I won't--people just randomly trying to find some predictability. Then we get texts. We get the 22-letter alphabet. So now instead of relying on priests to read everything for us and hieroglyphs now we can make our own words. Then we get the printing press which in theory lets us instead of depending on a few scribes now anyone can write. And then we get the computer which of course means now anyone can program reality.".

It's sad how many otherwise intelligent people are stuck in the muck of twisted medieval history which is lamentably overlooked and often taken for granted.
