AngularJS (1.x)
Two-way binding magic that became a migration tax. Angular 2+ was a rewrite; the 1.x apps lingered for years.
AngularJS faded because the 2.0 breaking rewrite stranded millions of lines and goodwill. Two-way binding hid state bugs until apps grew hair. It taught the world SPAs; React harvested the graduates.

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.
