I try to not be too grumpy about new tech or framework decisions (or old tech that's being rebranded as new!) because sometimes IT IS just because I don't have the bandwidth to keep up on everything but I'm just so tired of React. I don't want to use server actions. I don't want to use RSC. I want to do anything else. Please, very few are going to use these well. I don't feel like we advanced at all from the days of spaghetti code that people tried to convince us we were saved from with React.
"Don't you remember how awful it is having jQuery slung every where and trying to keep everything in sync and the mess of code it created?" YEAH HAVE YOU SEEN WHAT PEOPLE ARE DOING NOW? LMAO please.
If I think back to like, 10 years ago, the progression in the world of CSS has DRASTICALLY changed the way I build a UI for a website as a huge net positive good. Less code. Less images. Less clunky weird code. I really do not feel the same way about the advancements in JS UI libraries. I really don't think there has been a net positive good. Drastically different? Yeah, sure. But drastically BETTER? No, I don't think so.

@hbuchel IMO, this is because React does not actually represent advancement any longer, and hasn't for a very long time.

From my point of view, the very real fatigue you're experiencing and describing is not actually from truly modern JS; it's from the hardly-at-all modern Meta monster the industry refuses to move past, even though it's antiquated and inefficient by almost any measurable metric.

tl;dr: modern JavaScript is actually pretty great, but React isn't that.
