I think almost any technology gets to the "this is stupid" point. Not it "was" stupid, but it is. We understand something so well, we know that despite being useful it is fundamentally flawed. This is not usually verbal knowing, but initially more from an intuition and understanding a pattern. I have used react, it was certainly a better choice than the alternatives. I like it. But it is now "stupid", at least for me. And why? Because my whole web paradigm has been changed by "mobile first". What is mobile, and here I am talking iPhone and "good" Android? It is a good processor with tiny screen and really good graphics processor. You can run pretty good games on many/most phones. So why not use that 3D technology instead of html, css? Or at least in addition to. If you play around for react-three/{fiber,drei} for a little bit it feels like you have burst out of a straitjacket.
I once was told to make a product "cool" and after struggling to understand what "cool" even meant, I came to an idea. Things are cool if they make it so you never see the world the same way again. react-three/{drei,fiber} and threejs are cool. [For example https://r3f.docs.pmnd.rs/getting-started/examples]
These are cool demos, I agree, and they definitely show a glimpse of what the future of the web could look like. Right now though, pretty much all of them take ages to load, then spin my fans up as they run at low fps. And this is on a dev laptop, can't imagine what they're like on mobile or an older device.
