Absolutely.

Typescript + Next.js + Electron would be much, much faster for me to develop for than GTK + C, and even than Python + PyQT.

I wish there existed a modern cross-platform open source reactive GUI framework which was less of a resource hog than Electron, that would be great! Qt specifically is not much more economical, though the redistributable is smaller. Java is also rather nice for cross-platform GUIs, and also rather a hog.

Sadly, Electron is not so outstanding wrt resource consumption :-/
