I was thinking something similar: if "not fun" means "Ruby is becoming a stable, documented, performant language that can be used for real work" then I, for one, welcome our new adult overlords.

(Of course, there's still a long way to go until those criteria are satisfied, so I suppose it's still somewhat fun. Maybe not dance-around-naked-with-a-lampshade-on-your-head fun, but then, Zed's moved on...)
