When he said "switching to Scala" I reckon he probably meant "rewriting our platform."

It's very difficult to do a comparison like this in practice, because switching languages inherently involves a rewrite of a platform.

I am curious how much a rewrite staying in Ruby could have saved. Its always easier to write code when you have a good specification, and a working application would fulfill that role well.
