Why JavaScript lasted

  • It is the only language the web runtime will not let you uninstall.
  • Every attempt to replace it (Java applets, Flash, Dart-in-Chrome, Wasm-only apps) became a compile target for it instead.

Why Python lasted

  • It became the second language of every field: science, ops, ML, teaching, glue.
  • The packaging story is a mess and people still choose it, which is a kind of proof.
