This will make branded, OS-specific UI frameworks mostly irrelevant.
There will be less of platform lock-in. Users will be free to migrate between platforms, as most applications will be avaliable on multiple platforms by default. UI/UX will become independent of a platform's brand. This will lead to increased use of alternative OSes among casual users.
Now self-contained apps are becoming a thing, which solves the problem Java apps had in the past.
That said, Flutter did solve one problem better than competing alternatives in my opinion, which is that it is cross-platform and GPU-accelerated and has a small runtime.
Typical WebGL + WASM solutions need a 10 MB JavaScript download, which makes them unsuitable for regular websites. Flutter, on the other hand, is small enough to use both as a website and as an app.
If thats part of the criteria then I'll take the bet provided I am alive and solvent at the time.
My reasoning is that Spatial Computing is going to substantially progress the world of open web UI using WebGPU & WASM in ways that are not connectable to your assumed native primacy of scroll bars and menu elements as stated.
While similar arguments exists between Web and client side XR applications based on FPS & polygon counts, it doesn't mean that WebXR can't "build apps that are actually better for the end user" and do it better than with existing web frameworks. That even remains true if Apple ends up being a lone immersive web standard unto itself, intentionally hobbled at the knees to promote either Experience Quality or App Store lock-in. Not ideal but not removing the ability for WASM & WebGPU to run some novel XR workloads everywhere else in which case I'll be interested to see what $1000 looks like adjusted for inflation in 10yrs although a lawyer might argue the language points upto 2041, the technical end of the next decade.
I've been keeping my eye on what the Godot UI team has been up to and it looks like a pretty good starting point. But I think an evolution of UI input and interactivity is among us so fingers crossed we're going into a second (or 3rd depending on who you ask) UI renaissance... Or maybe were just looking at another "famous framework"
This is the biggest downside IMO. If web moves from readable HTML documents to WASM apps, many things will be lost.
No guess on the naming style of those frameworks?
