As I said below, if you tread off the full-stack-track, you get a lot of the go-like things in Ruby as well.

My point being: I usually rate architectural changes as more important as a change in development details (and the programming language might be a big one there, but it still is one, IMHO).

I'll tell you why: a lot of the sentiments people bring when they now switch from Ruby to Go, I've heard before. When people started Ruby - I was already doing Ruby for ~2 years before Rails even came out at it got me into the position of saying: "just you wait until you see the bad parts". They attributed a lot of things to Ruby, while they were really changing their development model.
