You are of course entitled to your opinion. And you're free to code apps for any platform or language you like.
Clearly though the world is using the web platform for writing applications. And I for one like the fact I can book a car, buy a secondhand book, or leave a restaurant review from a generic place that just works on all my devices.
See, that's where we went wrong. IMO the web is for web sites. Co-opting the browser for full applications has led to the significant degradement of modern software. If we must have a "write once, run anywhere" approach for modern development, can we at least use WASM bytecode and build a dedicated runtime that doesn't use the browser for GUI output?
