Better than maintaining vanilla JS applications that reinvented React for no d*mn reason. At least there's a massive pool of engineers who could jump into an old project and work on it right away, rather than wading through some clever engineer's buggy attempt at a view state management system.

Popular backend templating systems face the same problem with possible sunsetting and decay of collective knowledge over time.

React is a great investment, and is here to stay for a long time because its team (and community) are massive, and are keeping pace with newer libraries/frameworks that are in a lot of ways doing things better. React's market share has hardly been touched by Vue, Svelte, Solid, etc. and less so by HTMX and other new attempts at un-frameworking the web.
