Ruby is used a lot for sysadmin, systems management stuff (more than Python, surprisingly, because of good tooling). It's also used for stuff like iOS development (RubyMotion), and general purpose scripting.
That said, _is_ there anything of importance happening "outside of the web" nowadays?
Seriously??? You can't swing a cat without hitting someone singing the praises of "Big Data". We're at a point where machine learning is moving from academia out into "real world" in a major way. Statistics, data analysis and simulation is playing a more and more significant role in more and more fields every day. Both GIS and BIM, while still pretty niche, are growing rapidly in importance in their respective fields. I could go on all day. I'd almost (but not quite) say web frameworks is least important or interesting thing happening these days.
Which I also consider BS. I've seen tons of those "can't swing a cat without hitting X" fads in my time come and go, at best staying small niches.
