The quote 'Data is the sword of the 21st century, those who wield it the samurai.' is a bad metaphor. I'll let the cracked authors explain why.
Samurai Were Actually Embarrassed of Their Swords
Oh, come on. This, at least, just has to be bullshit. A quick Google image search of "samurai" returns a gazillion results, 99 percent of which depict the famed warriors with sword in hand. There are drawings about them using swords. There are photos. Hell, pajamas, katanas, and weird hairstyles were their whole thing: Samurai damn well lived by the sword. What else did they have?
Yes, the samurai did have an ancient tradition centered around a weapon. However, it sure as shit wasn't the sword. In fact, ignore every movie and video game about samurai, because they only carried swords as awkward last resort weapons.
Kyuba no michi, "the way of the horse and bow," was there centuries before any semblance of Bushido. It's exactly what it says on the tin: Samurai were all about flinging arrows at peasants from horseback. It makes sense, really -- they were professional soldiers, and in that line of business you quickly learn that only idiots fight the enemy at stabbing distance. Bows were revered over swords to the extent that many Japanese nobles actually downplayed their swordsmanship. After all, pointing out how great your sword skills were was basically announcing that you're a terrible archer. And saying "I'm a terrible archer" was more or less like saying "I'm neither a man nor a warrior."
The introduction of firearms in the 16th century finally killed the samurai supremacy as mounted archers. As they left the battlefield and settled for a new life as bureaucrats and officials, their formerly reviled swords started taking on actual importance as elaborate status symbols. And because bows weren't really an option anymore, the sword became the go-to weapon of the honorable, sword-wielding, bushido following and completely fictional samurai they retroactively invented to feel better about their crummy desk jobs.
Maybe it's an unintentionally good metaphor. Big data is the new useless but symbolic catchphrase that you use to make your company look modern.
