 The tradeoff we're making here is that `<ProfileTimeline>` will be inconsistent with other components and potentially show an older item. Click "Next" a few times, and you'll notice it. But thanks to that, we were able to cut down the transition time from 1000ms to 300ms.
 
-Whether or not it's an appropriate tradeoff depends on the situation. But it's a handy tool, especially when the content doesn't change very visible between items, and the user might not even realize they were looking at a stale version for a second.

 It's worth noting that `useDeferredValue` is not *only* useful for data fetching. It also helps when an expensive component tree causes an interaction (e.g. typing in an input) to be sluggish. Just like we can "defer" a value that takes too long to fetch (and show its old value despite others components updating), we can do this with trees that take too long to render.
