Pre-llm era Tailwind was great for the backend people who did not want to learn CSS. Nowadays agents got this. Openprops might be a good option even with agents, at least for me it works well. Not a surprise that Tailwind popularity dropped significantly.

I think the another llm-victim is React. For a while it was great to have a heavy framework that somewhat standardised webdev's JS approach. Astro just become the default goto lightweight option that is great to quickly build a nice simple UI.
