React enjoyed its spot in the limelight. Then, unskilled people wrote bad React and the framework, not rank-and-file developers, took the credibility hit. It is more difficult, I suppose, to make a user-perceived slow webpage in jQuery.

I dispute this. I don't have any statistics either, but my subjective experience is that most websites are not like newspapers or blogs. Even shopping websites have pretty heavy interactivity these days.

Also, most boring pure-information-presentation problems are mostly solved by ancient technologies like wordpress. If you're working in web development in 2026, you probably aren't making static websites or blogs. You're doing something novel that probably has much higher interactivity demands.
