That could be a sign of “stability”.
I’m personally using Django since two years ago and have the same feeling as yours, there are nothing exciting happening in this area, but after two years of use I came to the conclusion that it’s features are too stable, so nothing new need to happen in the first place.
It’s a common myth that software should be always updating and introducing new features. No, it’s not, if it can solve the problem great it doesn’t need to change at all.
JS/TS/Rust are still in their exploration phase, new ideas, new exprimentations, new frameworks come and go everyday, and that’ the reason they look vibrant.
Before settle down with Django, for years I’ve used bleeding edge tech like Meteorjs/React/Nextjs/Vue/Nuxtjs/Svelte/SvelteKit/… in real world, or try to rewrite real world app with them, and the biggest problem of all of them is that they all have their quirks and things in JavaScript area are changing too often and too much, I’m so tired to chase all these fancy new ideas.
For 90% web apps Django+Htmx+AlpineJS can serve me good and do all the things that new tech can do easily, at the same time keep incredible stability.
I believe Rails or Laraval are same here, you don’t need to switch in 90% cases, just relex and appreciate the stability they bring.
