"Is There Any Truth to the Claim That Einstein Was a Fraud?"
To summarize the article: "no."
Here's an entire article on Slate's link bait tendencies: http://matthewdicks.com/2013/11/benedikt-ridiculous-offensiv...
As for Swift, which Slate compares to Clojure, OCaml, and Scala, one difference is that exactly _none_ of those languages have native support for Cocoa APIs, something you might care a lot about if you're an iOS or OS X developer.
Swift is new, but Slate is not. Total nonsense.

I suppose time will tell if they made a good choice there, but I tend to think that open source languages will always win over proprietary languages, as they can adapt faster, and get much larger community adoption. It's a pity, because Swift looks pretty nice.
