This is where the paradigm shift is coming. Your past experiences say it must be a desktop native app, but I believe things like WASM, web workers etc will allow such things to run comfortably in the browser.

I really do believe people will build for the browser more than they will for the desktop because it's a more universal platform.

I can even imagine a future where, for the majority, the only native app you have on your machine is a browser, and everything else is some variant of a PWA. I really feel this will happen very soon.

This sounds like a nightmare.

Why? I can't wait for this world where everything can run on Linux.
