The real culprit here is UI. Yes, there are many better languages and runtimes than JS without a doubt. But most of their UI libraries are just as terrible if not more terrible than HTML/CSS/JS. And that is because developing sensible but also flexible and easy-to-use patterns for user-reactivity and data-presentation is HARD.

So sure, start a clean new operating system with a clean language with a clean runtime. I don't look forward to using whatever mess of a UI toolkit that gets built on top of it.

To add on top of that HTML/CSS/JS is really only serious open/free not owned by any for profit org cross platform UI toolkit. That is why Electron is quite popular.
