From a Kara Swisher reality check (the associated "NYT Picks" comments are also noteworthy):
"The arms race metaphor is a good one, but not for the reasons Facebook intended. Here’s how I see it: Facebook, as well as Twitter and Google’s YouTube, have become the digital arms dealers of the modern age.The Expensive Education of Mark Zuckerberg and Silicon Valley -- NYT
All these companies began with a gauzy credo to change the world. But they have done that in ways they did not imagine — by weaponizing pretty much everything that could be weaponized. They have mutated human communication, so that connecting people has too often become about pitting them against one another, and turbocharged that discord to an unprecedented and damaging volume.
They have weaponized social media. They have weaponized the First Amendment. They have weaponized civic discourse. And they have weaponized, most of all, politics."
