alt Hacker NewsI think there's plenty of developers that are perfectly competent with CSS who still reach for Tailwind.
You're right that Tailwind throws away the cascade, or at least enables developers not to have to think about it (under the hood, Tailwind 4 uses pretty modern cascading features like layers), but people aren't reaching it because of a lack of understanding, they're reaching for it because as front-ends get increasingly componentized, the cascade becomes less and less of a benefit and more of an obstacle to be worked around, and something that gets that obstacle out of the way becomes more attractive.
I'm perfectly competent at CSS and... at this point I don't even look at CSS. I just feed descriptions of what I want to the LLM and it nails it every time. The result either looks the way I want or it doesn't.
I'm not universally pro-AI. I meticulously review every line of backend code, and still do hand edits. I review FE commits less carefully but still keep an eye on it to make sure AI doesn't go off the rails. But there's only so much trouble you can get into with CSS and the problems are the kind of bite-sized problems that LLMs excel at.
I don't think it matters at this point what you use for styling. If you like tailwind, the AIs use it just fine. If you like SASS, or raw CSS, the AIs are also just fine.
I'm not sure there's really a human job here anymore.
