Argues that React hooks are overused and each extra hook increases real complexity, giving concrete failure modes: misuse of useEffect as a grab-bag (even to submit forms) causing surprising cascades like 30,000 renders, keeping derived state instead of calculating it, and misapplying useMemo/useCallback as fake optimizations. Recommends using useEffect only for external synchronization, treating useMemo as a way to provide stable references rather than free speedups, and creating custom hooks only when they encapsulate genuinely reusable logic rather than hiding messy code.
