Language · 2011–now · Platform Wars
Dart
Google's language that found purpose as Flutter's syntax. Rare case where the UI framework rescued the language.
Dart stuck because Flutter made cross-platform mobile credible with one codebase and hot reload. The language alone never competed with TypeScript or Kotlin for mindshare. Adoption follows Flutter job posts; admiration follows widget trees.

Context
Frameworks fought for the runtime
Front-end frameworks consolidated power; TypeScript became the floor; serverless and Jamstack rebranded old ideas with better CDNs. Blockchain-for-CRUD and big-bang rewrites collected the decade’s dumbest budgets. The winners were boring platforms with ecosystems. The losers were narratives that skipped product-market fit.
