Css in js was like a fever dream that lasted 2-3 years and seems to mostly go away. It's a good example as to how the frontend world just seems to make bad decisions.

Like if you take React's server components, it has a ton of problems and gets excessive focus from react devs, but fundamentally I can agree on what's its trying to solve. I understand the need, even if i disagree in almost anything else regarding it. I still don't know what the css in js phase was about.
