State management beyond the libraries
summary
Argues that the real state question is identities vs values and shows concrete tools and demos: MobX automatic dependency tracking that re-runs only affected derivations (arrows redraw minimally), Immer draft -> immutable next state which shrinks reducers to a single line with a three‑character fix, and a Remi PoC exposing cursors plus a map‑reduce materialized view that avoids full remaps. Each demo runs and demonstrates the performance and semantic tradeoffs.
