Ruby
Programmer happiness as a language feature. Rails made it famous; the language identity is older and quieter than the framework.
Ruby stuck in niches where expressiveness and metaprogramming pay rent — DSLs, ops tooling, and shops that still ship Rails. It failed as a hyperscale default after Twitter-scale cautionary tales over-generalized. Admiration outruns hiring pools outside the Rails belt.

Context
The browser ate the desktop
The web became the default delivery surface. LAMP and Rails made shipping cheap; Ajax made pages feel like apps; SOAP/SOA tried to enterprise-ify the wire. REST won by being debuggable with curl. This decade invented the modern product cadence — and the habit of treating every new framework as destiny.
