The power of WordPress is not the ease of use, but PHP.
Anything built on PHP will be widely used, like Laravel
All PHP is going to be replaced with single binary Rust apps.
Talented teams will build the atoms for most apps - blogs, CMSes, ticket systems, forums - and it'll be easy for end users to configure.
Rust is easy to code gen and deploy now. No barrier to understanding lifetimes. It's the language everyone should be using Claude Code to emit.
Everyone is now a Rust engineer with 10 years of experience. (I'm not joking, just in case that needs clarification.)
If you haven't tried writing a simple web service in Axum or Actix plus SQLx, you need to give it a try. You'll be amazed at how simple it is, and you'll be even more amazed at how performant and easy it is to work with.
You do not need to know Rust or have any prior Rust experience. You'll pick it up along the way. It's easy and you'll learn it fast.
Rust is a low-defect rate language to serialize to. The syntax begs you to handle errors, nulls, exceptional conditions within the language itself. This is naturally a good fit for most business problems. It doesn't hurt that the language is fast as hell and super portable either.
If the job is now encoding business logic - this is the optimal serialization that I'm aware of. I write Go, Java, Python, TypeScript, PHP, Swift - I can't think of any better language for greenfield projects that don't have existing language/library requirements.
That used to be a major selling point because hosts enabled PHP for a directory devs would FTP things into, but those days are thankfully long gone. I don't think it's any more difficult to host a JS, TS, or anything else, app than it is to host a PHP app today. In fact, PHP is probably more difficult than something like Netlify.
