My concern about all of this is that it might lead to basically two ruby communities; Rails and Rails devs will mostly keep writing type free code (dhh has always indicated he's not a fan of types), but a lot of other rubyists will gradually introduce types into their code. This could create two different ecosystems with different gems, best practices, blogs etc etc etc. We will see how it plays out but I'm quite conflicted about this one. The good thing is that it's optional.
