Ember.js
Convention-over-configuration SPA framework. LinkedIn and Discourse kept the faith; everyone else went React.
Ember faded because it optimized for long-lived enterprise SPAs while the market wanted hireable React freelancers. It was opinionated in the right ways but shipped heavy defaults in the era of bundle-size audits. Survivors swear by it; newcomers never arrive.

Context
Split everything, then pay for the glue
Hyperscale patterns escaped the companies that needed them. Containers unified packaging; Kubernetes became the cloud OS; microservices and NoSQL were sold as defaults. Mobile-first stuck because screens changed. Cargo-cult distributed systems stuck around as invoices. The durable move was packaging and ops maturity — not rewriting every app into a mesh.
