Functional programming gets closer to the mainstream
"If you consider that companies like Facebook, Google, and Amazon represent where the rest of the internet is going—as the internet grows, so many other online services will face the same problems it faces today—Facebook’s Haskell project can indeed point the way for the programming world as a whole. That doesn’t mean Haskell will be ubiquitous in the years to come. Because it’s so different from traditional programming languages, coders often have trouble learning to use it; undoubtedly, this will prevent widespread adoption. But Facebook’s work is a sign that other languages will move in Haskell’s general direction.
Indeed, they already are. Newer languages such as Google Go and Mozilla’s Rust are designed so that developers can build massively parallel code and build it at speed. And as Brandy points out, other projects are building Haskell-like software libraries for additional languages, including “reactive” programming projects like RxJava."Facebook's New Spam-Killer Hints at the Future of Coding | WIRED
