There are a lot of React state libraries that do similar things with Proxies. I think the part that is not as emphasized is how that reactivity extends to the view. Instead of re-rendering components it uses that knowledge to directly update portions of the DOM. So while MobX, Valtio, Jotai, Recoil etc localize change in React, they still feed into the whole VDOM React cycle, instead of just updating exactly what changes. It's not a characteristic of these libraries but the fact they feed into React.

Solid very much seems like "what would happen if somebody took the way I usually combine react + mobx and built something designed for that from the ground up".

The only thing it doesn't obviously do better is the JSON Patch generation stuff that I get from mobx-state-tree and I use the word obviously because it would not at all to surprise me to discover that solid already does that and I simply didn't RTFM hard enough yet.

The sheer level of ecosystem (and the "nobody ever got fired for" advantage that results) may keep me using react but solid is a bloody impressive piece of kit and whether I ever end up using it myself or not, "bravo, sir" applies.

Though you can use smaller components to minimize the changes. Valtio i feel is one of the simplest of those. But yes they are no way compared to solidjs. Of the numerous frameworks in recent years solidjs has the only which has interested me to pick up and use it. Though still not in production.
