I write plenty of declarative UI too in the form of SwiftUI (where it makes sense; often on Apple platforms the imperative frameworks are better suited) and Jetpack Compose.

Declarative UI has its upsides, but it’s hardly a panacea. There are places where it’s a straightforward dramatic improvement and then others where it’s an awkward contortion at best. Reactivity can be great but works in imperative setups too.

The explosion of popularity of front end web frameworks comes down almost entirely to two things: accessibility and commodity talent. It has a low bar to entry and JS+React is the closest the industry has come yet to achieving its undying dream of cheap, easily replaceable, interchangeable developers. In most other aspects it’s objectively worse than alternatives.
