React was a massive improvement over Ember.js, Backbone.js and their ilk, which at the time as a young dev I couldn’t grasp by myself.

React, however just clicked. f(state) = UI just makes sense

Which is not at all how it works in practice. In a large React codebase you have state scattered throughout contexts, GraphQL caches and complex hook dependency trees.

Throw in SSR and component memoization and you really have no idea what caused a UI change to occur.
