Twitter transitioned to Scala to continue writing beautiful code
I found this quote in this article about Twitter moving to Scala:
> But he also prefers Scala because it's, well, beautiful. "It's a fuzzy thing. But we like writing beautiful code, code that you're proud of, code that you can show to non-programmers and they get it."
They chose Scala because they wanted to write "beautiful code." I think I can say that Ruby influenced this decision in more ways than one.
