I'm not sure I'd say "React Bad", I'd rather say "React Not Really Super Necessary and More Often Than Not Leads to a Worst Experience at Maybe a Slightly Lower Initial Cost" :)

I did an experiment recently, I actually wanted to launch a dashboard and picked React because I knew I could throw React + Tailwind + popular_component_and_charts_frameworks at Opus and get a decent result. But actually, I realized a lot of fairly simple button clicks had like a 100ms-200ms delay, and I just did not like it. I ported it to Java/Javalin with J2HTML and kept tailwind, and it's very snappy and works great. It's currently 96k lines of java ^_^
