Mobile-first / Responsive
Design for the small screen first. Became table stakes, not a differentiator.
Mobile-first stuck because traffic followed phones and CSS finally made responsive layouts cheap. It stopped being a fad when ignoring it meant losing customers. Now it is hygiene, not thought leadership.

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.
