One of the promises of using hooks was that you wouldn't have to care about things being recreated every render. Gone were the days of complex update logic in lifecycle methods like `componentWillUpdate()`, `componentWillReceiveProps()`, `componentDidReceiveProps()` etc. Now you use clean, functional components everywhere, even if they needed local state. No kludge, just clean code.

But most of the production functional React code I see is sprinkled so liberally with complex `useCallback()`, `useMemo()` and `useRef()` calls to prevent unnecessary updates that it seems just as bad as before. Worse, sometimes, because the hooks pattern can encourage more indirection. I still find myself thinking all the time about object references in state, cloning vs. mutating, dependency arrays with 5, 6, 7 distinct dependencies.

Honestly, I don't know if it's any better than it used to be. At least the `componentDidReceiveProps()` logic tended to all be in one place.
