Fear of bloated webapps taking over the world is maybe paranoia, but well placed paranoia at that. It's not the fault of the tools though, it's the developers who have a terrible mindset. You can argue that the "system" encourages this, but I think it could just be growing pains and incompetence. We're in the teenager phase of the web, in my opinion.

I also have an argument against the "too many languages" point: What's happening in the modern web is that HTML, CSS, and JS are slowly combining. A lot of projects are moving towards TSX components (Typescript and React, Vue, Svelte, etc.) with Tailwind CSS. So: Typing, layout, scripting, and styling all in one cohesive package that can easily be abstracted into components or classes.

I think eventually there will be a singularity of sorts where we have a standard toolkit/language.

From my own experience building websites and native apps, I can move around in web tech like a god damn ninja but I hate electron. I hate the inefficiency of using a browser for the UI. Qt and Gtk feel clunky and limited compared to web, but are native. But now there's Tauri, and I think it's a large step in the right direction.
