Point 1 in this article is totally misguided. "State management is how you mitigate prop drilling" implies that when prop drilling is not a problem (i.e. most of the time), that you don't need to think about state management. Even if you're prop drilling, you need to make sure data is not stored/updated in multiple places in your app in order to keep the UI consistent.

The one redeeming part of that section of this article is that it links to another article that isn't as wrong. The linked article details when prop drilling is and isn't a problem. And most of the problems it describes can be reduced by using TypeScript. https://kentcdodds.com/blog/prop-drilling
