Excuse my lack of expertise but I don't like web as a platform. Isn't it basically Javascript (an now WASM) + CSS on the client side and a browser as the VM?

On all platforms web is a second class citizen and the feature set is the common denominator which means it's always lacking something. It doesn't have access to all the hardware, it runs in a VM (which I assume means it is slower) and the dev languages are meh.

I prefer something along the lines of what Fuschia promises. That is, ephemeral software that gets downloaded lazily and runs natively as a first class citizen of the underlying OS
