SPAs designed to mirror state on the server have a distributed data problem, there are lots of problems there in terms of fetching, updating, ensuring the users are traversing from action, loading, success/failure etc Then there's the problem that the page could have changed since the user started filling out that form, what happens when those form values now conflict etc etc The difference between serving a dead fish of a HTML page, and a SPA application is vast because you're essentially creating 2 independent systems, server and client instead of just server and then adding one of the hardest thing in computing which is consensus between disparate systems I'm quite excited about React Server Components because it means for the majority of your web app you can return to the simplicity of shipping HTML it doesn't solve everything but at the moment client side applications have a lot of boilerplate to do with just keeping the server in sync that would have been historically "for free" in a server context
